14 Day Old Autoflower: What Your Cannabis Plant Should Look Like at Week 2

A 14 day old autoflower is still very young, but this is one of the most important stages in the plant’s life. By the end of week 2, the plant has moved past the earliest seedling phase and is starting to build the structure it will use for the rest of its growth. At this point, growers often want to know if the plant looks normal, if it is growing fast enough, and if anything needs to be changed. These are smart questions, because autoflowers grow on a fixed timeline. Unlike photoperiod cannabis plants, autoflowers do not wait for changes in light to begin flowering. They grow quickly, and each early day matters.

To understand why day 14 matters so much, it helps to know what an autoflower is. Autoflower cannabis plants are bred with genetics from Cannabis ruderalis. This type of cannabis is known for its ability to flower based on age instead of light schedule. That means the plant starts moving through its life cycle on its own. For growers, this can be helpful because autoflowers are often faster to finish than photoperiod plants. However, it also means there is less time to recover from stress. If a plant struggles during the first two weeks, it may stay smaller for the rest of its life. That is why growers pay close attention to the week 2 stage.

At 14 days old, an autoflower should no longer look like a tiny sprout with only a few leaves. In most cases, it should be entering early vegetative growth. The stem should be a little stronger, the root system should be spreading, and several sets of true leaves should be visible. The plant is still small, but it should show steady progress. Healthy growth at this stage usually means the leaves are green, the stem is upright, and the plant is making new growth from the center. It may not look large yet, but it should look alive, balanced, and active.

This is also the point when many growers start comparing their plants to pictures online and asking if their plant is too small or too slow. That is very common. The truth is that not all 14 day old autoflowers look exactly the same. Some strains grow faster than others. Some stay short and compact. Others stretch more in the early days. A plant grown in perfect indoor conditions may look very different from one grown outdoors in cool weather. Even two seeds from the same pack can show small differences. Because of this, growers should not judge a plant only by height. It is better to look at the whole picture, including leaf color, stem strength, node development, and overall health.

The first two weeks are important because the plant is doing several things at once. Above the soil, it is making leaves and building its shape. Below the soil, it is forming roots that will feed the plant later. Strong root growth during this stage is very important. If the roots are healthy, the plant can take in water and nutrients more easily. This supports faster and stronger growth in the weeks ahead. If the roots stay too wet, too dry, or damaged, the whole plant can slow down. That is why simple choices like pot size, watering habits, and soil texture can make a big difference very early.

Growers should also understand that week 2 is a stage where mistakes can start to show. Overwatering is one of the most common problems. Young autoflowers do not need large amounts of water, and soggy soil can reduce oxygen around the roots. Poor lighting can also slow growth. If the light is too weak, the plant may stretch and stay thin. If the light is too strong, the leaves may curl, droop, or show stress. Feeding too early can also hurt a young plant. Many beginners think more nutrients will create faster growth, but small autoflowers often need only light feeding at first, especially in rich soil.

At the same time, this stage is not only about avoiding problems. It is also about building a strong base. A healthy 14 day old autoflower is preparing for the next phase of growth. In week 3 and beyond, the plant will usually start growing faster. More leaves will form, the stem will thicken, and the plant will begin to take on a fuller shape. The better the care during week 2, the better the chance the plant has to stay healthy through the rest of its short life cycle.

In simple terms, the 14 day old autoflower stage is a checkpoint. It gives growers a chance to see whether the plant is on track. A healthy plant at this point does not need to be huge, but it should show steady growth, healthy color, and good structure. This stage matters because autoflowers do not have much time to recover from setbacks. What happens in the first two weeks can affect plant size, vigor, and final yield later on.

For that reason, growers should use day 14 as a time to observe, not panic. The goal is to understand what normal early growth looks like and what signals a problem. Once a grower knows what to expect, it becomes much easier to make smart choices about water, light, nutrients, and environment. That knowledge can help turn a small week 2 plant into a healthy and productive autoflower in the weeks ahead.

What Does a 14 Day Old Autoflower Look Like?

A 14 day old autoflower is still very young, but it should no longer look like a brand-new seedling. By the end of week 2, the plant is usually moving from the seedling stage into early vegetative growth. At this point, growers want to see steady development above the soil and healthy growth below it in the root zone. While each plant can look a little different, there are some normal signs that show an autoflower is developing well.

Typical height range of a two-week-old autoflower plant

At 14 days old, most autoflowers are still small. Many healthy plants are around 2 to 6 inches tall, though some may be a little shorter or taller depending on the strain, light level, temperature, container size, and watering habits. A compact plant is not always a bad sign. In fact, many healthy autoflowers stay short in the first two weeks while they build strong roots and tight node spacing.

A plant that is very tall and thin at day 14 may not be growing in the best way. This can happen when the light is too weak or too far away. In that case, the seedling stretches upward as it tries to get more light. On the other hand, a short plant with a firm stem and tight leaf spacing often shows that the lighting is strong enough and the plant is growing with good structure.

Height by itself does not tell the whole story. A healthy 14 day old autoflower should look balanced. It should not seem weak, floppy, or unusually stretched. The plant should look stable in its growing medium, with leaves reaching outward and upward rather than hanging lifelessly.

Number of leaf sets commonly present at this stage

By week 2, a normal autoflower often has several sets of true leaves. The first round leaves, called cotyledons, may still be present, although they can start to fade as the plant becomes more established. Above those, growers usually see at least 2 to 4 sets of true leaves, and in some fast-growing plants there may be even more.

The earliest true leaves usually have a single blade. After that, the plant starts making leaves with more fingers. As it grows, the newer leaves begin to look more like the classic cannabis leaf shape. At 14 days, the top of the plant should show fresh new growth. This is a good sign that the plant is active and continuing to develop.

The number of leaf sets can vary from one plant to another. Some strains naturally grow faster, while others take a bit more time. Cooler temperatures, low light, poor soil conditions, or overwatering can also slow leaf production. What matters most is that the plant is adding new growth in a steady way and that the leaves look healthy.

Appearance of healthy stems and leaves

A healthy stem at day 14 should be upright and firm. It may still be thin, but it should be able to support the plant without falling over. The stem should not look soft, pinched, or weak. Its color is often light green, though some plants may show slight purple tones from genetics or cooler temperatures. A strong stem helps support future growth, so this early structure matters.

The leaves of a healthy autoflower should look fresh, open, and evenly colored. In most cases, they will be medium green to bright green. Leaves should not be heavily curled, twisted, droopy, or spotted. Small differences can happen, but major changes in color or shape often point to a problem with water, nutrients, temperature, or light.

The leaf surface should look smooth and full, not dry or damaged. New growth in the center should be clear and easy to see. When a plant is doing well, the leaves often angle slightly upward during the day, which can be a sign that the plant is responding well to its environment.

Differences between seedlings and early vegetative growth

At the start of life, an autoflower is in the seedling stage. During this phase, it is very small and delicate. It depends on its early root growth and stored seed energy to get established. The stem is thin, the plant has only a few leaves, and growth may seem slow at first.

By day 14, many autoflowers begin to show signs of early vegetative growth. This means the plant is starting to grow faster and build more structure. It develops more leaf sets, stronger stems, and a wider shape. The plant begins to look less like a fragile sprout and more like a young cannabis plant.

This shift matters because the plant is getting ready for its next phase of development. Since autoflowers have a short life cycle, early growth is especially important. They do not have as much time to recover from stress as photoperiod plants. A good-looking plant at week 2 often has a better chance of growing into a healthy and productive plant later.

Visual signs of a strong and healthy plant

A strong 14 day old autoflower usually has a few clear visual signs. It stands upright and looks stable in the pot or soil. Its leaves are green, open, and free from major damage. The newest growth appears healthy and continues to form at the top of the plant. The stem looks firm enough to support the plant, and the space between nodes is not too wide.

The plant should also look symmetrical overall. While perfect symmetry is not required, the plant should have a fairly even shape. Uneven growth, severe leaning, or badly deformed leaves can point to stress. Healthy young autoflowers usually look simple, neat, and active. They may still be small, but they should look alive and strong.

Another good sign is steady change from day to day. At this stage, a healthy autoflower often looks a little bigger every morning. New leaves become easier to see, and the plant starts to fill out. Even if growth seems modest, regular progress is a better sign than sudden fast growth followed by drooping or discoloration.

A 14 day old autoflower should look like a young but established cannabis plant. It is usually small, often around 2 to 6 inches tall, with several sets of true leaves and a firm upright stem. Healthy leaves should be green and open, and the plant should show fresh new growth at the top. At this point, the plant is moving beyond the seedling stage and into early vegetative growth. Growers should focus less on exact size and more on overall health, balance, and steady development.

How Big Should a 14 Day Old Autoflower Be?

A 14 day old autoflower is still very young, so it should not be expected to look large or fully developed. At this point, the plant is still building its roots, stem, and first sets of true leaves. Many new growers worry when their plant looks small after two weeks, but small size at this stage does not always mean there is a problem. What matters most is that the plant is healthy, growing steadily, and showing normal structure for its age.

Average Size at Two Weeks

Most 14 day old autoflowers are usually around 2 to 6 inches tall. Some may be a little shorter, while others may be slightly taller. This range is normal because growth can change based on strain, light, temperature, pot size, and watering habits. Some strong and fast-growing plants may reach about 7 inches by day 14, but many healthy plants stay on the smaller side during this stage.

Height alone does not tell the full story. A short autoflower can still be healthy if it has a thick stem, green leaves, and steady new growth. A taller plant is not always better. Sometimes a plant that grows too tall too early is stretching because it needs stronger light. That is why growers should look at the full plant, not only the height.

At two weeks, many autoflowers have a few sets of true leaves and several nodes starting to form. The stem should look firm enough to support the plant. The leaves should be open, green, and shaped normally. Even if the plant is still small, these signs show that it is moving in the right direction.

Why Size Can Vary Between Strains

Not all autoflowers grow at the same speed. Genetics play a big role in how large a plant becomes during its first two weeks. Some strains are naturally compact and stay short early on. Others have faster vegetative growth and may look larger by day 14.

Indica-leaning autoflowers often stay shorter and bushier. They may have wider leaves and tighter spacing between nodes. Sativa-leaning autoflowers may grow a little taller with longer spaces between leaf sets. Hybrid strains can show a mix of these traits. Because of this, two healthy autoflowers of the same age can look very different from each other.

Seed quality also matters. Strong seeds often produce stronger seedlings. If a seed had trouble sprouting or came from weak genetics, the plant may start slower. This does not always mean the grow will fail, but it can affect plant size at the two-week mark.

Environmental Factors That Affect Plant Size

The growing environment has a major effect on how big an autoflower gets by day 14. Light is one of the most important factors. If the plant gets enough light, it can grow with better speed and stronger structure. If the light is too weak or too far away, the plant may stretch upward and become thin. If the light is too strong, the plant may become stressed and slow down.

Temperature also affects growth. Autoflowers usually do best when the environment is warm but not hot. If the grow space is too cold, the plant may grow slowly. If it is too hot, the plant may lose water too fast and become stressed. Humidity matters as well, because young plants need enough moisture in the air while their root systems are still developing.

The growing medium can also change plant size. Loose, airy soil helps roots spread more easily. Heavy or packed soil can slow root growth, which slows the whole plant. Good drainage is important too. If water sits too long around the roots, the plant may stop growing well.

Container size can make a difference. Autoflowers often do best when planted directly into their final pot because they do not like too much stress. If roots become cramped too early, growth may slow down. A healthy root zone supports healthy top growth.

Why Some Autoflowers Grow Faster or Slower

Some plants simply grow faster than others, even when they are given the same care. One reason is root development. During the first two weeks, autoflowers put a lot of energy into building roots. A plant with strong root growth may look small at first, then grow much faster later. Another plant may show more leaf growth early but have weaker root support underneath.

Feeding also affects growth speed. At day 14, young autoflowers do not usually need heavy nutrients. Too much fertilizer can burn the plant and slow its progress. A mild feeding plan or rich soil is often enough early on. Plants that receive too many nutrients too soon may stay smaller because they are recovering from stress.

Watering habits are another major reason for slow or fast growth. Overwatering is one of the most common mistakes with young autoflowers. When the medium stays too wet, roots cannot get enough oxygen. This slows root growth and causes the plant to stay small. Underwatering can also slow growth, though young growers more often overwater than underwater.

Signs That Growth May Be Stalled

A 14 day old autoflower may be smaller than expected without being unhealthy, but there are signs that suggest a real growth problem. If the plant has not changed much in several days, this may mean growth has stalled. A very thin stem, pale leaves, drooping leaves, curling edges, or spots on the leaves can all point to stress.

A plant that is under 2 inches tall at day 14 may need closer attention, especially if it also looks weak or discolored. Slow growth can come from weak light, poor soil, root stress, bad watering habits, or temperature problems. Growers should check these conditions one by one instead of making too many changes at once.

It is also important to avoid panic. Many growers hurt their plants by reacting too quickly. Adding more nutrients, more water, or more light all at once can make the problem worse. Slow, careful adjustments are safer and usually more effective.

A healthy 14 day old autoflower is often around 2 to 6 inches tall, but size can vary a lot. Genetics, light, temperature, soil, watering, and root health all affect how big the plant will be at this stage. Some plants grow fast, while others stay smaller as they build strong roots. Instead of focusing only on height, growers should look for healthy leaves, a steady growth pattern, and a firm stem. At two weeks, steady progress matters more than big size.

What Stage of Growth Is an Autoflower at Day 14?

At day 14, an autoflower is usually moving out of the seedling stage and into early vegetative growth. Some growers still describe this as the late seedling stage, while others call it the start of early veg. Both labels point to the same idea: the plant is no longer just a fresh sprout, but it is not yet a large vegetative plant either. By this point, the autoflower is using more energy to build leaves, stems, and roots, which prepares it for the rest of its short life cycle.

The Shift From Seedling to Early Vegetative Growth

During the first days after sprouting, a cannabis plant is in the seedling stage. This is when it depends on its first small leaves and begins basic photosynthesis. By around day 14, a healthy autoflower usually has several sets of true leaves and stronger growth above the soil. This is why many grow guides place week 2 at the edge between the late seedling stage and early vegetative growth. The plant is now focused less on simple survival and more on building its structure.

This stage matters because autoflowers grow on a fast internal clock. Unlike other types of cannabis plants, they do not stay in the vegetative stage for a long time. Many autoflowers begin flowering naturally about three to six weeks after germination. Because of this, the second week is an important window for healthy early growth. If the plant struggles now, it has less time to recover before flowering begins.

What the Plant Is Doing Above the Soil

At day 14, the plant is building its early framework. The stem begins to thicken, the leaves start to spread wider, and new nodes form as the plant prepares for faster growth. The goal at this point is not flower production. Instead, the plant is creating the green material it will need later for photosynthesis and energy production.

Week 2 is when the plant starts building its structure. You may notice that a healthy 14-day-old autoflower begins to look more balanced and upright than it did during the first week. The early round seed leaves have already done their job, and the true leaves now handle most of the plant’s energy production. The plant should look small but active, with steady development coming from the center growth point.

Root Development at Week 2

Even though growers often focus on the leaves first, a large part of week 2 growth happens below the soil surface. During this stage, the root system expands quickly. Strong roots help the plant absorb water, oxygen, and nutrients. They also support the plant’s structure as it grows taller and produces more leaves.

This root growth explains why some plants may not appear very large above the soil at day 14 but are still healthy. A plant may spend a lot of energy developing its root system first. When the roots become strong and well spread, the plant often begins to grow faster above the soil. Because of this, steady development is usually more important than rapid height growth at this stage.

How Autoflowers Differ From Photoperiod Plants at Day 14

At first glance, a 14-day-old autoflower and a 14-day-old photoperiod cannabis plant can look similar. Both may have several nodes, multiple sets of leaves, and a small but growing root system. The main difference between the two types is how they move into the flowering stage.

Photoperiod plants stay in the vegetative stage until the light cycle changes. Growers can keep these plants in vegetative growth for a long time by maintaining long light periods. Autoflowers behave differently. They do not depend on changes in light cycles to begin flowering. Instead, they start flowering based mostly on age.

Because of this, week 2 is more time-sensitive for autoflowers. Photoperiod plants can recover from early stress by staying in vegetative growth longer. Autoflowers have less time to recover because their life cycle moves forward automatically. This is why growers often try to reduce stress during the first few weeks of an autoflower’s life.

Why This Stage Is Important for Later Growth

Day 14 is an important foundation stage for an autoflower plant. During this period, the plant develops the leaves, stem strength, and root mass it will depend on later. Since many autoflowers begin transitioning toward pre-flowering not long after week three or four, the progress made during week 2 can influence plant size and future flower production.

Proper care during this stage includes providing stable lighting, balanced watering, and a healthy growing environment. When these conditions remain stable, the plant can focus its energy on steady development instead of recovering from stress.

Growers should not expect to see flowers at day 14. Instead, they should look for signs of healthy vegetative growth. These signs include steady new leaf development, a thicker stem, and balanced plant structure. When these features are present, the plant is usually developing normally.

At day 14, an autoflower cannabis plant is usually transitioning from the seedling stage into early vegetative growth. The plant is strengthening its stem, producing new leaves, and building an expanding root system below the soil. This stage forms the foundation for the rest of the plant’s life cycle. Because autoflowers grow quickly and begin flowering based on age, healthy development during week 2 plays an important role in supporting strong growth in the weeks that follow.

How Many Leaves Should a 14 Day Old Autoflower Have?

At 14 days old, an autoflower usually does not have a fixed number of leaves that every plant must match. That is the first thing growers need to understand. Cannabis does not grow on an exact schedule like a machine. Even when two plants come from the same seed pack, one may grow a little faster than the other. What matters most at week 2 is not chasing one exact leaf count. What matters is whether the plant is making steady progress, forming healthy new growth, and moving from the seedling stage into early vegetative growth. During the first one to two weeks, cannabis seedlings form true leaves while roots begin to establish. After that, the plant starts to grow more stems, branches, and leaves as it enters vegetative growth.

A Normal Leaf Pattern at Day 14

A 14 day old autoflower often has its round seed leaves, also called cotyledons, plus several sets of true leaves. The cotyledons are the first small leaves that appear after germination. They do not look like normal cannabis leaves. After those, the plant begins making true leaves with serrated edges. In the earliest stage, these true leaves may appear simple and small. As the plant continues to develop, the leaves become more complex and begin to show the classic cannabis shape more clearly.

A healthy week 2 autoflower often has a few clear sets of true leaves and is starting to look more like a small cannabis plant instead of a fresh sprout. Some plants may still look compact and small, while others may already be pushing out new growth from the center at a faster rate. Both can be normal if the plant looks healthy overall.

Understanding Nodes and Leaf Sets

When growers talk about how many leaves a plant should have, they often also mean how many nodes it has. A node is the place on the stem where leaves and future branches grow. Counting nodes is often more useful than counting every single leaf. That is because one node can hold a pair of leaves, and the plant builds its structure node by node as it matures.

At around day 14, many autoflowers are still in the late seedling or very early vegetative stage. That means the plant is focused on building a small but important structure. It is making new nodes, expanding its leaf area, and strengthening its root zone. During the first two weeks of life, most cannabis plants are still developing their early structure before entering full vegetative growth.

A plant with fewer leaves is not always unhealthy. It may simply be growing a bit slower because of cooler temperatures, less intense light, transplant stress, or genetics. On the other hand, a plant with more leaves is not always better if those leaves are pale, twisted, droopy, or burnt.

What Healthy Leaves Should Look Like

The look of the leaves matters more than the number alone. Healthy leaves on a 14 day old autoflower are usually green, open, and slightly angled toward the light. The stem should also look firm enough to support the top growth. New leaves at the center should appear fresh and active. The plant should not seem stuck in place for many days.

At this point, growers want to see even growth. Leaves should not be badly curled, clawed, or heavily spotted. Mild variation in shape can happen, but strong deformities may point to stress. If the oldest leaves are still green and the new growth looks clean, that usually means the plant is using its energy well.

Why Leaf Count Can Vary

There are several reasons why one 14 day old autoflower may have more leaves than another. Genetics is a big one. Some autoflower strains grow fast and push through the seedling stage quickly. Others stay short and stocky at first. Growing conditions also change leaf production. Light intensity, temperature, humidity, root space, and watering habits all affect how quickly new leaves form.

Leaf count can also vary because of the plant’s stage of development. Seedlings gradually shift from a juvenile phase to a stronger vegetative phase. During this time, leaf shape and node development change as the plant matures. This means that early leaves may be simple and small, while later leaves become larger and more complex.

This is why a grower should avoid comparing one plant too closely against a photo online. Pictures can be helpful, but they do not show the full story of the plant’s genetics, age from sprout, or growing environment.

When to Be Concerned

A low leaf count may be a concern if the plant also shows weak color, very slow growth, drooping, or damage on new leaves. If the plant has barely changed for several days, the problem may be overwatering, poor root oxygen, weak light, or stress in the growing medium. A healthy plant should show visible progress during this period, even if that progress is modest.

It is also important to remember that autoflowers have less time to recover from early setbacks than photoperiod plants because they move through their life cycle quickly. That makes week 2 an important time to keep conditions steady and avoid mistakes.

A 14 day old autoflower should usually have its cotyledons and several sets of true leaves, but there is no perfect leaf number that every plant must reach. A better way to judge the plant is to look for steady new growth, healthy green leaves, and normal node development. At week 2, the plant is moving from the seedling stage into early vegetative growth, so some variation is normal. If the leaves look healthy and the plant is still developing day by day, it is usually on the right track.

What Nutrients Does a 14 Day Old Autoflower Need?

At 14 days old, an autoflower is still very young. It is no longer a brand-new seedling, but it is not yet a large plant with heavy feeding needs. This is the stage where many growers make mistakes. Some give too many nutrients too soon. Others give none at all, even when the plant starts to ask for more. The best approach is usually simple, careful, and balanced.

A two-week-old autoflower mainly needs a healthy root zone, mild nutrition, and stable growing conditions. If the plant is in rich soil, it may already have enough food for now. If it is in coco coir or another low-nutrient medium, it may need light feeding much earlier. The key is to understand what the plant needs at this stage and not force fast growth with strong nutrients.

Why nutrition matters at week 2

By day 14, an autoflower is moving from the seedling stage into early vegetative growth. During this time, the plant starts building more leaves, a thicker stem, and a wider root system. To do this, it needs access to the right nutrients in the right amount.

Nutrients help the plant make chlorophyll, grow new tissue, move water, and support root strength. Without enough nutrition, growth can slow down, leaves can lose color, and the plant may stay small. With too much nutrition, the roots can become stressed, leaf tips can burn, and the plant may stop growing well. Since autoflowers have a short life cycle, losing time early can reduce the final yield later on.

That is why week 2 is an important stage. The plant is still small, but it is starting to grow faster. Good nutrition supports that change, but mild feeding is usually safer than heavy feeding.

The basic nutrients young autoflowers need

Cannabis plants need three main nutrients in larger amounts. These are nitrogen, phosphorus, and potassium. Many growers call them NPK. At 14 days old, the plant usually needs a little more nitrogen than the other two because it is focused on leaf and stem growth.

Nitrogen helps the plant stay green and build new leaves. It supports fast, healthy vegetative growth. If a young autoflower does not get enough nitrogen, its leaves may look pale or light green, and growth may slow down.

Phosphorus is important for roots and energy transfer inside the plant. A 14 day old autoflower still needs phosphorus, especially because root development is very active at this stage. Healthy roots help the plant absorb water and nutrients better.

Potassium helps with overall plant strength, water movement, and stress response. It also supports strong stems and healthy growth. Even though nitrogen is very important in week 2, the plant still needs all three major nutrients in balance.

Secondary nutrients also matter

Young autoflowers also need secondary nutrients, especially calcium, magnesium, and sulfur. These may not get as much attention as NPK, but they are still very important.

Calcium supports cell wall strength and healthy new growth. It helps the plant build strong tissue in stems and leaves. A lack of calcium can lead to twisted new growth, weak leaves, or other early problems.

Magnesium is needed for chlorophyll production. Since chlorophyll gives leaves their green color and helps the plant use light, magnesium is important even at a young age. If magnesium is low, leaves may start to yellow between the veins.

Sulfur helps with plant metabolism and supports healthy development. It is needed in smaller amounts, but it still plays a role in balanced growth.

Many growers see early plant problems and think the issue is always nitrogen. In some cases, the real problem is calcium or magnesium, especially in coco or when using filtered water with very low mineral content.

When should you start feeding nutrients?

There is no single answer for every grow. The right time depends on the growing medium, the pot size, and the health of the plant.

If the autoflower is growing in rich soil, it may not need added nutrients at day 14. Many quality soils already contain enough nutrition for the first two to three weeks. In this case, adding extra feed too early can do more harm than good.

If the plant is growing in coco coir, rockwool, or a light soil mix with little nutrition, feeding often starts earlier. By day 14, a mild nutrient solution may be needed to support growth. This is because those growing media do not hold much natural food for the plant.

The safest way to begin is with a light dose. Many growers start with about one-quarter to one-half of the normal feeding strength. A young autoflower is more sensitive than a larger plant, and it can react badly to heavy feeding. It is easier to add a little more later than to fix nutrient burn after the damage starts.

Why overfeeding is a common mistake

One of the biggest problems at this stage is overfeeding. Growers often want the plant to grow faster, so they give more nutrients than the plant can handle. This can stress the roots and slow growth instead of helping it.

Signs of overfeeding may include burnt leaf tips, very dark green leaves, curled leaf edges, or drooping after feeding. In some cases, the plant may stop growing as expected. Since autoflowers have a short vegetative period, any setback can matter.

Young plants do not need strong feedings. Their root systems are still developing, and they absorb nutrients differently than mature plants. Strong nutrient mixes can build up in the root zone and create more problems than benefits.

A healthy 14 day old autoflower should usually be fed lightly and watched closely. If the leaves stay green, growth is steady, and the plant looks strong, there may be no reason to increase feeding right away.

Common nutrient deficiencies at day 14

Although overfeeding is common, underfeeding can also happen. This is more likely in coco, poor soil, or when pH problems block nutrient uptake.

A nitrogen deficiency often shows as pale green older leaves and slow growth. Since nitrogen moves through the plant, the lower leaves usually show signs first.

A calcium deficiency may appear in new growth. The leaves may look twisted, spotted, or uneven. This is often seen in fast-growing young plants or in media that need extra calcium.

A magnesium deficiency can cause yellowing between leaf veins, often on older leaves first. The leaf may still have green veins while the area around them becomes lighter.

Phosphorus problems may cause slow growth, dull leaves, or darker color than normal. Potassium issues may show as weak growth or leaf edge damage later on, though they are less common this early unless feeding is badly unbalanced.

It is important not to guess too quickly. Overwatering, wrong pH, poor root health, and cold temperatures can all look like nutrient problems. Before adding more feed, growers should check the full growing environment.

pH and nutrient uptake

Even if the right nutrients are present, the plant may not be able to use them if the pH is out of range. This is called nutrient lockout. At 14 days old, a small autoflower can be affected quickly by poor pH.

In soil, cannabis usually absorbs nutrients best in a slightly acidic range. In coco or hydro systems, the target range is also slightly acidic, though the exact range may differ. If the pH is too high or too low, the roots may struggle to take in calcium, magnesium, nitrogen, and other important nutrients.

This is why pH matters just as much as the feed itself. A grower may think the plant is hungry, when the real issue is that the nutrients are present but locked out.

A 14 day old autoflower needs mild, balanced nutrition and a careful hand. At this stage, the plant usually needs nitrogen for leaf growth, phosphorus for roots, potassium for strength, and important secondary nutrients like calcium and magnesium. Some plants in rich soil may not need added feed yet, while plants in coco or low-nutrient media may need a light feeding. The biggest risk is overfeeding, which can stress a young autoflower and slow its growth. The best results usually come from starting light, watching the plant closely, and making small changes only when needed.

Ideal Light Conditions for a 14 Day Old Autoflower

Light is one of the most important factors in the early growth of cannabis plants. At 14 days old, an autoflower plant is moving from the seedling stage into early vegetative growth. During this time, the plant begins to build more leaves, stronger stems, and a larger root system. Proper lighting helps the plant produce energy through photosynthesis, which allows it to grow healthy and strong.

Because autoflowers grow on a fixed timeline, it is important to give them the right light conditions from the beginning. Mistakes in lighting during the first two weeks can slow growth and reduce the plant’s overall potential.

Recommended Light Cycles for Autoflower Cannabis Plants

Autoflower cannabis plants do not depend on light cycles to begin flowering. Unlike photoperiod plants, they do not need changes in daylight hours to trigger the flowering stage. Because of this, growers often provide longer light cycles to help maximize growth.

A common light schedule for autoflowers is 18 hours of light and 6 hours of darkness each day. This schedule gives the plant a long period of light for growth while still allowing a short rest period. Some growers also use a 20 hours on and 4 hours off schedule. Both approaches can work well for a 14 day old autoflower.

The goal is to provide steady and consistent light each day. Sudden changes in lighting can stress young plants. Consistency allows the plant to maintain stable growth and healthy development during the early vegetative stage.

Appropriate Light Intensity During Week Two

At two weeks old, an autoflower plant is still small but growing quickly. The plant needs stronger light than a newly sprouted seedling, but it should not be exposed to extremely intense light yet.

Moderate light intensity works best at this stage. The plant should receive enough light to grow compact and healthy, but not so much that the leaves begin to show signs of stress. If the light intensity is correct, the plant will grow with short spaces between nodes and sturdy stems.

Grow lights such as LED panels or fluorescent lights are commonly used indoors. Many LED grow lights allow growers to adjust the intensity, which helps create the right conditions for young plants. If the light is adjustable, increasing intensity gradually during week two can support steady growth.

Distance Between Lights and Plants

The distance between the light and the plant is very important for a 14 day old autoflower. Lights that are too close can cause heat stress or light burn. Lights that are too far away may lead to weak growth and stretched stems.

For many LED grow lights, a distance of about 18 to 24 inches above the plant is often suitable during early vegetative growth. Fluorescent lights may be placed closer because they produce less heat. However, the exact distance can vary depending on the power of the light being used.

A good way to judge the correct distance is to observe the plant carefully. If the plant grows tall and thin with long spaces between leaves, the light may be too far away. If the leaves curl upward, become pale, or show signs of dryness, the light may be too close.

Signs That Lighting May Be Too Strong or Too Weak

A 14 day old autoflower often shows clear signs when lighting conditions are not ideal. Plants that receive too little light may stretch upward as they try to reach the light source. This results in long stems and weak structure.

On the other hand, light that is too strong can damage young plants. Leaves may curl upward or develop dry edges. In some cases, the top leaves may appear bleached or faded in color. These are signs that the plant is receiving more light than it can handle.

Healthy plants usually show steady growth with bright green leaves. The plant should look compact and balanced rather than stretched or stressed. Observing the plant daily helps growers make small adjustments before problems become serious.

Differences Between Indoor and Outdoor Lighting Conditions

Indoor growers control light using artificial grow lights. This allows them to provide consistent lighting every day. The light schedule, intensity, and distance can all be adjusted based on the plant’s needs. Indoor growing environments make it easier to maintain stable conditions for young autoflowers.

Outdoor plants rely on sunlight instead of artificial lighting. Sunlight is strong and full spectrum, which supports natural plant growth. However, outdoor lighting conditions change throughout the day and across different seasons.

At 14 days old, outdoor autoflowers should receive several hours of direct sunlight each day. Placing the plant in an area with good sunlight exposure helps it grow strong and healthy. At the same time, very intense heat or harsh midday sun can sometimes stress young plants, especially in hot climates.

Growers may choose a location where the plant receives strong morning light and partial shade during the hottest part of the day. This balance helps protect the young plant while still giving it enough energy to grow.

Light plays a major role in the development of a 14 day old autoflower. At this stage, the plant benefits from a consistent light schedule, moderate intensity, and proper distance from the light source. Most growers use an 18 hour light cycle to support strong vegetative growth.

Healthy lighting conditions help the plant grow compact, develop strong stems, and produce vibrant green leaves. Watching the plant closely for signs of stretching or light stress allows growers to make quick adjustments. When the lighting environment is balanced and stable, a two-week-old autoflower can continue growing steadily and prepare for the next stages of development.

Watering a 14 Day Old Autoflower Correctly

Watering a 14 day old autoflower can seem simple, but this is one of the easiest ways to harm a young cannabis plant. At two weeks old, an autoflower is still small above the soil, but it is working hard below the surface. Its root system is still forming, and that means the plant cannot handle the same watering routine as a larger cannabis plant. Many growers make the mistake of giving too much water too soon. Others wait too long and let the root zone become too dry. The goal is to keep the growing medium lightly moist, not soaked and not bone dry.

At this stage, the plant does not drink large amounts of water. A 14 day old autoflower usually has only a few sets of true leaves, and its roots are still spreading through the pot. Because of that, it is better to think carefully about where and how often you water instead of just pouring water on a schedule. Young autoflowers grow best when the roots get both moisture and oxygen. When the soil stays too wet for too long, the roots struggle to breathe. When the soil gets too dry, the young plant can slow down and become stressed.

How Often a 14 Day Old Autoflower Usually Needs Water

There is no single rule that fits every plant, because watering depends on the pot size, soil type, temperature, humidity, and light strength. A young autoflower in a warm grow room with strong light may need water sooner than a plant in a cooler room with softer light. A plant growing in a light, airy soil mix may also dry out faster than one in dense soil.

Instead of watering on the same day every time, it is better to check the medium first. The top layer of soil may look dry, but the lower area may still hold enough moisture. A good grower learns to judge the pot before watering again. If the container still feels heavy, there is likely still enough water inside. If it feels much lighter, the plant may be ready for more. This simple habit helps prevent overwatering, which is one of the most common problems at week two.

Many growers water in a small ring around the plant instead of soaking the whole pot. This helps the roots search outward while still getting enough moisture near the base. It also keeps the entire container from staying wet for too long, which lowers the chance of root stress.

Why Overwatering Is Such a Common Problem

Overwatering does not always mean giving too much water in one sitting. It often means watering too often. Even a small amount of water can become a problem if the soil never gets a chance to dry enough between waterings. At 14 days old, the root zone needs air as much as it needs water. If the medium stays wet all the time, the roots can become weak, and the plant may stop growing well.

A young autoflower that is overwatered may look droopy, but the leaves often feel heavy and full rather than thin and dry. The plant may seem slow, pale, or stuck in place for several days. New growth may come in slowly, and the stem may not thicken as expected. Some growers see drooping leaves and assume the plant is thirsty, so they add even more water. This often makes the problem worse.

Good drainage is very important here. A pot should let extra water escape easily. The growing medium should also contain enough air pockets to support healthy root growth. If the soil is too compact, water can stay trapped, and the roots may struggle.

How to Spot Underwatering

Underwatering can also slow down a 14 day old autoflower, though it is usually easier to fix than overwatering. When a plant does not get enough water, the leaves may droop in a softer way and may feel lighter or thinner. The soil may pull away from the sides of the pot, and the container may feel very light. Growth can slow, and the leaves may lose some of their healthy, upright look.

A plant that goes too dry too often may stay smaller than it should. Autoflowers have a short life cycle, so early stress matters. Unlike photoperiod plants, they do not have as much time to recover from repeated mistakes. That is why it is important to keep moisture levels steady instead of letting the plant swing between very wet and very dry conditions.

Best Watering Practices for Small Cannabis Plants

The best way to water a 14 day old autoflower is with care and control. Give water slowly so the medium has time to absorb it. Do not flood the pot. Focus on the area around the seedling while slowly widening the watering area as the plant grows. This supports root expansion without leaving the whole container soaked.

It also helps to water at the right time of day. Indoor growers often water when the lights are on, since this is when the plant is active. Outdoor growers usually water in the morning, which gives the plant time to use the water during the day. Watering late in the day can sometimes leave the medium too cool or too damp for too long.

Water quality matters too. Very poor water can create problems even when the watering amount is correct. Clean water with a suitable pH helps the plant absorb nutrients better and supports healthy root development. At week two, small problems in the root zone can quickly show up in the leaves.

As the autoflower grows, its water needs will increase. The routine that works at day 14 will not be the same routine that works later in vegetative growth or in flowering. That is why close observation matters. Watch the plant, feel the pot, and respond to what the plant actually needs instead of following a fixed schedule.

Watering a 14 day old autoflower is all about balance. The plant needs enough moisture to support root and leaf growth, but it also needs oxygen in the root zone. Watering too often can slow growth and cause drooping, while watering too little can lead to dryness and stress. The best approach is to check the medium before watering, use small and controlled amounts, and adjust based on the plant’s environment. When watering is done correctly at week two, the autoflower has a much better chance of growing strong and healthy in the weeks ahead.

Temperature and Humidity for Week 2 Autoflowers

At week 2, an autoflower is still very young. It is no longer a brand-new sprout, but it is not yet a strong, fully established plant either. This is why temperature and humidity matter so much at this stage. A 14 day old autoflower grows best when the air around it stays steady and mild. If the space gets too hot, too cold, too dry, or too damp, growth can slow down fast.

Young autoflowers do not handle stress as well as older plants. Since autoflowers move on a fixed life cycle, lost time in week 2 can affect the rest of the grow. A plant that struggles early may stay small later. For that reason, growers should focus on keeping the environment stable every day.

Ideal Temperature Range for Early Vegetative Growth

A 14 day old autoflower usually does best in a warm but not hot environment. In most cases, a daytime temperature of about 70 to 80 degrees Fahrenheit works well. In Celsius, that is around 21 to 27 degrees. This range gives the plant a good balance. It is warm enough to support active growth, but not so warm that the plant starts to stress.

At night, a small drop in temperature is normal and can even be helpful. Many growers aim for around 65 to 72 degrees Fahrenheit, or about 18 to 22 degrees Celsius, during the dark period. A small difference between day and night is fine, but a large drop can shock a young plant.

If the temperature stays below the ideal range for too long, the plant may grow slowly. Leaves may look droopy, and the roots may not develop well. Cold conditions can also make it harder for the plant to take in water and nutrients. On the other hand, if the grow space gets too hot, the leaves may curl, edges may look dry, and the plant may lose moisture too fast.

The main goal is not just hitting the perfect number once in a while. The goal is to stay in a safe range most of the time. A steady 75 degrees is usually better than going from 65 to 85 over and over again.

Recommended Humidity Levels During Week Two

Humidity is also very important for a 2-week-old autoflower. Since the root system is still small, the plant still takes in some moisture from the air through its leaves. This is why young plants often do better with higher humidity than older plants.

A relative humidity level of around 60 to 70 percent is often a good target during week 2. This range helps the plant hold moisture without drying out too quickly. It also supports healthy leaf growth while the roots continue to spread.

If humidity is too low, the plant may lose water faster than it can replace it. This can lead to slow growth, curling leaves, or a weak overall look. The plant may seem thirsty all the time, even when the root zone is not actually dry.

If humidity is too high, problems can also appear. The growing medium may stay wet for too long, airflow may become poor, and harmful fungi may have a better chance to grow. While very young plants like more humidity than mature ones, there still needs to be balance.

In simple terms, week 2 autoflowers usually like air that feels slightly moist, not dry and not heavy.

How Climate Conditions Affect Plant Development

Temperature and humidity work together. One affects the other, and both influence how the plant grows. Warm air can hold more moisture than cool air. This means that a room that seems fine at one temperature may become too dry or too damp when the temperature changes.

When the climate is right, the plant can focus on growing new leaves, building roots, and strengthening the stem. Photosynthesis works well, water moves through the plant properly, and nutrient uptake is smoother. This creates the base for better growth in the coming weeks.

When the climate is wrong, the plant uses energy to deal with stress instead of using that energy for growth. Even a healthy seedling can slow down if the room is unstable. A young autoflower may not show damage right away, but the stress can still reduce its later size and yield.

This is why growers should not look at temperature, humidity, watering, and lighting as separate topics. They all connect. For example, strong light can raise leaf temperature. Higher heat can lower humidity. Lower humidity can cause faster water loss. One issue can quickly turn into several issues.

Ventilation and Airflow Considerations

Fresh air and gentle airflow are very helpful for week 2 autoflowers. Plants need carbon dioxide from the air to grow. If the air in the grow space becomes stale, growth can slow down. Good ventilation helps replace old air with fresh air and helps control both heat and humidity.

A small fan can also help strengthen stems and reduce damp spots around the plant. The key word is gentle. The airflow should move the leaves slightly, not push them hard. If the fan is too strong, the plant can dry out or develop wind stress. Leaves may look twisted, droopy, or damaged even when the temperature seems fine.

Exhaust fans, intake vents, and clip fans can all play a role in creating a healthy grow space. In a small indoor tent, even a simple setup can make a big difference. Outdoors, airflow usually comes naturally, but weather changes can make conditions harder to control.

Good airflow also helps prevent mold, mildew, and pest issues. Areas with trapped heat and moisture often become problem spots. Even at week 2, it is smart to keep air moving and avoid crowded conditions around the plant.

Environmental Stress Factors to Avoid

Week 2 autoflowers can react quickly to poor conditions. One of the biggest stress factors is sudden change. A room that swings from hot to cold or from dry to damp can confuse the plant and slow development. Autoflowers do best when the environment stays as steady as possible.

Heat stress is common under strong grow lights. If the lamp is too close, the top of the plant may become too warm even when the room temperature seems normal. Leaves may taco upward, curl, or look faded. Raising the light or improving airflow often helps.

Cold stress is also a concern, especially at night or in colder rooms. A plant exposed to repeated low temperatures may stay small and weak. Roots are especially sensitive to cold growing media.

Low humidity can make leaves dry and thin. High humidity can make the medium stay wet too long, which raises the risk of overwatering and root problems. Poor ventilation can make all of these problems worse.

Another stress factor is placing the plant near heaters, air conditioners, or direct drafts. These can create microclimates where one part of the plant is warmer or cooler than the rest. Even if the room average looks fine, the plant may still suffer.

At week 2, an autoflower needs a calm and steady environment to grow well. A temperature range of about 70 to 80 degrees Fahrenheit during the day and slightly cooler at night usually works best. Humidity around 60 to 70 percent can support healthy early growth while the roots are still developing.

Good climate control helps the plant build leaves, roots, and stem strength. Gentle airflow and fresh air also support healthy growth and reduce the risk of mold, pests, and damp conditions. The most important thing is stability. A 14 day old autoflower will usually do better in a simple, steady environment than in a grow space that keeps changing.

Should You Train a 14 Day Old Autoflower?

Training is one of the most common topics growers search for when their plant reaches the two-week mark. At 14 days old, an autoflower is still very young. It is moving out of the seedling stage and into early vegetative growth. This is the point where many growers start asking whether they should bend, top, tie down, or otherwise shape the plant. The short answer is that training can help in some cases, but it must be done with care.

Autoflowers are different from photoperiod plants. They grow on a fixed timeline. That means they do not wait for a change in light cycle before they flower. Because of this, every day of early growth matters. If the plant gets stressed too much in week 2, it may not have enough time to recover before flowering begins. That is why training a 14 day old autoflower should always be gentle and well timed.

What plant training means

Plant training is the process of shaping a cannabis plant so it grows in a better way. The goal is often to improve light exposure, create more even growth, and increase the number of good bud sites later on. Training can also help control height, which is useful in small grow spaces.

Some growers train their plants so the canopy stays flat and open. A flat canopy means more parts of the plant can get direct light. This can lead to more balanced development across the whole plant. In autoflowers, this is often more important than making the plant very large. Since autoflowers have less time to grow, the goal is usually to make the best use of the plant’s natural shape instead of forcing major changes.

At 14 days old, the plant is usually still small. It may only have a few nodes and a young root system. Because of that, not every training method is a good fit yet.

Why heavy training is usually avoided at this stage

Heavy training includes methods that cut, break, or strongly damage plant tissue. The most common example is topping, which means cutting off the main growing tip. Other high-stress methods include super cropping and major defoliation. These methods can work on larger, stronger plants, but they are often too stressful for a 14 day old autoflower.

The main problem is recovery time. A photoperiod plant can stay in vegetative growth longer and recover from stress before flowering. An autoflower may begin flowering soon after this stage, depending on the strain and growing conditions. If a young autoflower spends several days recovering from damage, that lost time can reduce its final size and yield.

Heavy training at day 14 can also slow root development. At this age, the plant still needs energy to build a strong base. When a grower cuts or damages the plant too early, the plant may shift its energy into repair instead of growth. This can leave it short, weak, or uneven later on.

That does not mean no autoflower should ever be topped. Some experienced growers do it with strong, fast-growing plants. Still, it is not usually the safest choice for most growers at week 2. A small mistake at this stage can affect the whole life of the plant.

Low-stress training and how it works

Low-stress training, often called LST, is the gentlest form of plant training. Instead of cutting the plant, the grower bends and ties parts of it to guide growth. The purpose is to open the plant up and allow more light to reach lower shoots.

For a 14 day old autoflower, low-stress training is usually the safest method if the plant is healthy enough. A healthy plant should have a firm stem, several nodes, steady growth, and no signs of stress such as drooping, yellowing, or twisted leaves. If the plant is weak or stalled, it is better to wait.

LST often starts by gently pulling the main stem to one side and securing it in place. This changes the plant’s shape and encourages side branches to grow upward. Over time, the plant becomes wider and more even. Because the stem is only bent and not cut, the stress is lower than with topping.

Even with LST, the plant must be handled carefully. Young stems can bend, but they can also snap if too much force is used. The grower should make small changes and watch how the plant responds over the next day or two. Good training is gradual. It should never feel rushed.

Risks of stressing a young autoflower

A 14 day old autoflower can look healthy but still be more fragile than it seems. Stress at this stage can come from many sources, not only training. Overwatering, poor light, nutrient burn, transplant shock, heat, and low humidity can already put pressure on the plant. If training is added on top of those problems, the plant may struggle even more.

One major risk is stunted growth. A stunted autoflower often stays small through the rest of its life. Since the plant has limited time before flowering, it may never fully catch up. Another risk is uneven growth. If the main stem is damaged or bent too hard, the plant may develop in an odd shape that is hard to manage later.

There is also the risk of physical injury. A split stem, broken branch, or damaged leaf can slow the plant down. While cannabis can recover from small injuries, recovery is not always fast in autoflowers. This is why growers should always be gentle and avoid training when the plant is dry, weak, or already stressed.

When training may be appropriate

Training may be appropriate at day 14 if the autoflower is growing strongly and has reached a stable early vegetative stage. This usually means the plant has multiple nodes, a healthy green color, and active new growth. It should not be drooping or showing signs of poor health.

The best early option is light LST. This can begin once the stem is flexible enough to bend without damage. Some growers wait a few extra days until the plant is slightly larger, which can make training easier and safer. Timing depends on the strain, the environment, and how fast the plant is developing.

The key is to read the plant, not just the calendar. Two autoflowers can both be 14 days old but look very different. One may be strong and ready for gentle training, while another may still be too small. Age matters, but plant condition matters more.

A 14 day old autoflower can sometimes be trained, but it should be done with care. Heavy training methods like topping or super cropping are usually too stressful this early, especially for beginners. Autoflowers grow on a short timeline, so lost recovery time can hurt later growth.

Low-stress training is the better option if the plant is healthy, stable, and growing well. Gentle bending can improve light exposure and shape without causing major damage. The safest approach is to keep stress low, move slowly, and pay close attention to how the plant responds. At week 2, protecting healthy growth is more important than forcing major changes.

Common Problems With 14 Day Old Autoflowers

At 14 days old, an autoflower is still very young. This is one of the most sensitive parts of its life. The plant is trying to build roots, grow new leaves, and prepare for faster vegetative growth. Because of that, even small mistakes can cause visible problems. Some issues are easy to fix, while others can slow the plant for the rest of its life.

Autoflowers do not have as much recovery time as photoperiod plants. They grow on a fixed timeline, so stress during week 2 can reduce final size and yield. That is why it is important to spot problems early and understand what the plant is trying to tell you.

Slow Growth and Stunted Plants

One of the most common concerns at day 14 is slow growth. Many growers look at their autoflower and worry because it seems too small. A healthy plant at this stage should usually have a few sets of true leaves, a short but steady stem, and clear daily progress. If the plant looks stuck and does not seem to change much over several days, it may be stunted.

Stunted growth can happen for many reasons. Overwatering is one of the biggest causes. When the growing medium stays too wet, the roots do not get enough oxygen. This slows root growth, and when roots struggle, the whole plant struggles. Poor soil can also cause slow growth. If the medium is too dense, roots may have trouble spreading. If it is too hot with nutrients, the young plant may become stressed early.

Cold temperatures can also slow development. A young autoflower grows best in a warm and stable environment. If the room is too cold, the plant may grow very slowly. Weak lighting is another possible reason. If the plant is not getting enough light, it may not have the energy it needs to grow at a normal pace.

Transplant stress can also stunt an autoflower. Many growers prefer to start autoflowers in their final container because these plants do not always respond well to root disturbance. Even a short pause in growth at this stage can affect the plant later on.

Leaf Discoloration or Curling

Leaves can tell you a lot about plant health. At week 2, healthy leaves should look fresh, slightly broad, and green. If the leaves start to turn pale, yellow, or show strange marks, the plant may be under stress.

Yellowing leaves can have several causes. In some cases, the plant may be getting too much water, which can block normal root function. In other cases, the plant may need a light feeding, especially if the medium has very little nutrition left. A lack of nitrogen can lead to pale green color, though very young plants do not usually need heavy feeding.

Curling leaves can also point to trouble. Leaves that curl downward may suggest overwatering, excess nitrogen, or heavy stress. Leaves that curl upward at the edges can be a sign of heat stress or light stress. If the light is too close, the plant may try to protect itself by changing leaf shape. Dry air and poor temperature control can also make leaves twist or curl.

Brown spots, crisp edges, or uneven coloring may point to a calcium or magnesium issue, but these signs can also happen when pH is off. Even if nutrients are present in the medium, the plant may not be able to use them well if the root zone pH is out of range.

Nutrient Burn or Deficiency Symptoms

Many new growers make the mistake of feeding too early or too heavily. A 14 day old autoflower is still small and does not need strong doses of nutrients. If the plant gets too much food, it can show signs of nutrient burn. This often appears as burnt leaf tips. The ends of the leaves may turn yellow, bronze, or brown. In more serious cases, leaves may darken, curl, or look shiny and stressed.

Nutrient burn is a common problem because growers want to help the plant grow faster. But too much feeding often does the opposite. It can damage roots, slow growth, and create more stress.

On the other side, deficiencies can also show up in week 2, especially in inert media or poor-quality soil. A nutrient deficiency happens when the plant does not get enough of a needed element. Nitrogen deficiency often shows up as pale or yellow lower leaves. Calcium problems may appear as spots or weak new growth. Magnesium issues may cause yellowing between leaf veins.

Still, growers should be careful not to guess too fast. Many symptoms look similar. Overwatering, pH problems, and root stress can look like nutrient issues even when the real cause is somewhere else. That is why it helps to look at the full growing setup before adding more nutrients.

Environmental Stress Issues

Young autoflowers need a stable environment. Fast changes in temperature, humidity, or airflow can create stress very quickly. In week 2, the plant is still building strength, so poor conditions can slow growth and damage leaf health.

Heat stress is one major issue. If the grow space is too hot, leaves may curl upward, look thin, or lose their healthy green color. The plant may also dry out too fast. When this happens, growth can slow because the plant is using energy to survive instead of develop.

Cold stress is also harmful. When temperatures drop too low, the plant may stop growing properly. Leaves may droop, colors may fade, and water use may slow down. Cold root zones are especially bad for small plants.

Low humidity can be a problem as well. At 14 days old, autoflowers still prefer moderate humidity because they are not yet large enough to handle very dry air well. If humidity is too low, the plant may lose water faster than it can take it in. This can lead to drooping, curling, or slow growth.

Strong airflow can also damage a young plant. Good air movement is helpful, but a fan blowing directly on a seedling or young autoflower can cause wind stress. Leaves may twist, edges may look dry, and the stem may struggle instead of strengthen.

Pest Problems That May Appear Early in Growth

Pests can attack cannabis plants even when they are still young. At 14 days old, an autoflower has limited leaf mass and a small root system, so pests can do damage quickly. Common early pests include fungus gnats, spider mites, aphids, and thrips.

Fungus gnats are often linked to wet soil. The adults may seem harmless, but their larvae can affect root health. If the soil stays too moist, these pests can become a bigger problem. Spider mites and thrips attack leaves and can leave behind tiny spots, pale marks, or damaged tissue. Aphids may gather on stems or under leaves and feed on plant sap.

One reason pests are dangerous in week 2 is that the plant is too young to handle a major setback. A pest problem can reduce growth, weaken leaves, and open the door to more stress. Clean growing conditions help prevent this. It also helps to inspect leaves often, especially the undersides, and watch for unusual specks, bite marks, or moving insects.

At 14 days old, autoflowers can run into several common problems, including slow growth, leaf discoloration, curling, nutrient burn, deficiencies, environmental stress, and pest attacks. Because this stage is so early, problems should be handled carefully and quickly. The goal is not to force fast growth but to create steady, healthy growth. A strong week 2 plant should look green, balanced, and active. When growers learn how to read early warning signs, they can fix problems before they become bigger and protect the plant’s future development.

How to Encourage Faster Growth at Week 2

At week 2, an autoflower is still young, but it is no longer just a new seedling. This is the stage when the plant starts to build a stronger root system, grow more leaves, and prepare for faster vegetative growth. If conditions are right, a 14 day old autoflower can begin to put on visible growth from one day to the next. If conditions are poor, the plant may stay small, slow down, or show signs of stress.

The goal at this stage is not to force the plant to grow fast through heavy feeding or constant changes. The best way to encourage faster growth is to create a stable environment and let the plant grow without stress. Autoflowers have a short life cycle, so any setback in week 2 can affect the final size and yield later on.

Keep the Growing Conditions Stable

Stable conditions are one of the most important parts of fast growth. Young autoflowers do not respond well to sudden changes in temperature, humidity, watering, or light. Even if the change seems small, it can slow the plant down.

A healthy week 2 autoflower usually grows best when the temperature stays warm but not hot. If the room gets too cold, growth may become slow because the plant cannot carry out normal processes as well. If it gets too hot, the plant may become stressed and lose water too fast. Humidity also matters because young plants still take in some moisture through their leaves while their roots continue to develop.

Growers often make the mistake of changing too many things at once when they think a plant looks small. They may move the light, add nutrients, change the watering amount, and adjust the environment all in the same day. This can create even more stress. A better approach is to keep the environment steady and make small changes only when there is a clear reason.

Optimize Light Without Overdoing It

Light is one of the main drivers of plant growth. At week 2, an autoflower needs enough light to support leaf and stem growth, but the light should not be so intense that it causes stress. When the light level is correct, the plant can photosynthesize well and produce the energy it needs to grow faster.

If the light is too weak, the plant may stretch upward and become thin. The space between nodes may get too long, and the stem may look weak. If the light is too strong, the leaves may curl, droop, or look pale. In some cases, the plant may stop growing well because it is spending energy dealing with stress instead of building new growth.

The best setup is one where the plant gets a steady light schedule and the lamp is kept at a safe distance. This allows the leaves to stay open and healthy. A plant with flat, upright leaves and a compact shape is often getting a good amount of light. When the light is right, week 2 growth becomes more even and more predictable.

Feed Carefully and Do Not Rush Nutrients

A 14 day old autoflower does not usually need heavy feeding. In many cases, the grow medium already has enough nutrition for the first part of life. If extra nutrients are added too early or in too large an amount, the plant can suffer from nutrient burn. This often shows up as burnt leaf tips, dark leaves, or slowed growth.

To encourage faster growth, feeding should be gentle and based on what the plant actually needs. A young autoflower benefits from balanced nutrition, especially nutrients that support leaf growth and root health. Nitrogen is important at this stage because the plant is focused on growing green leaves and stems. Calcium and magnesium are also important because they help support healthy development.

The key is to avoid the idea that more nutrients always mean more growth. Young autoflowers are sensitive. Overfeeding often slows them down instead of helping them. A lightly fed plant in a good environment usually grows better than an overfed plant in a stressful one.

Support Strong Root Health

Fast growth above the soil depends on healthy growth below the soil. During week 2, roots are spreading into the growing medium and looking for water and oxygen. If the roots are healthy, the plant can take up what it needs and grow faster. If the roots are stressed, the top of the plant will show it.

One of the biggest threats to root health is overwatering. When the growing medium stays too wet for too long, the roots cannot get enough oxygen. This can lead to slow growth, drooping leaves, and weak development. Watering too often can be just as harmful as not watering enough.

Good soil structure also matters. A light and airy medium helps roots grow outward more easily. If the soil is too dense, roots may struggle to spread. That can slow down the whole plant. Healthy roots support healthy leaves, stronger stems, and quicker growth during this early stage.

Maintain Good Airflow and Proper Temperature

Airflow helps more than many new growers realize. A gentle movement of air around the plant helps control heat and humidity. It also helps the stem grow stronger. When the air in the grow space is stale or still, the plant may struggle with excess moisture, weak stems, or uneven temperature.

Week 2 autoflowers do best in an environment where fresh air can move in and warm, damp air can move out. This helps the plant stay comfortable and keeps the leaf surface in better condition for gas exchange. Good airflow also lowers the risk of some early plant problems linked to wet or trapped air.

Temperature works together with airflow. If the room is too cold, growth slows down. If it is too hot, the plant may curl or droop. A steady, moderate temperature helps the plant use water, light, and nutrients in a balanced way. This leads to stronger and faster growth over time.

Avoid Common Beginner Mistakes

Many slow-growing week 2 autoflowers are not weak because of genetics alone. They slow down because of avoidable mistakes. Overwatering is one of the most common problems. Another is feeding too soon or too heavily. Some growers also handle the plant too much, transplant at the wrong time, or try early training before the plant is ready.

Autoflowers do not have a long recovery window. Because they move from one stage to the next on their own schedule, stress in week 2 can have lasting effects. That is why it is important to keep things simple. Give the plant enough light, enough warmth, proper watering, and a clean environment. Then let it grow.

Patience is also important. Not every autoflower will look large at day 14. Some strains grow more compactly at first and then speed up later. The better question is not whether the plant looks huge right now, but whether it looks healthy, steady, and free from stress.

To encourage faster growth at week 2, focus on the basics and do them well. Keep the environment stable, give the plant the right amount of light, feed gently, protect root health, and maintain good airflow and temperature. Avoid overwatering, overfeeding, and other common mistakes that can slow a young autoflower down. At this stage, healthy growth matters more than fast growth alone. When the plant stays strong and stress-free in week 2, it has a much better chance of growing well in the weeks ahead.

Indoor vs Outdoor Growth at Day 14

At 14 days old, an autoflower cannabis plant is still in a very early stage of development. The plant is building its roots, strengthening its stem, and producing its first sets of true leaves. Even at this young stage, the growing environment can strongly influence how the plant looks and how quickly it develops.

An autoflower grown indoors often looks more uniform. Indoor growers can control light, temperature, humidity, airflow, and watering. Because these factors stay stable, the plant tends to grow in a consistent pattern. At day 14, an indoor plant may appear compact with evenly spaced nodes and healthy, symmetrical leaves. The stem is usually sturdy because the plant receives steady light and airflow.

Outdoor plants can look more variable at this stage. Two plants planted at the same time may look slightly different by the end of week two. This happens because outdoor conditions change daily. Sunlight levels, temperature swings, wind, and rain can all influence how quickly a plant grows. A healthy outdoor plant may still be slightly taller or less symmetrical than an indoor plant due to these natural changes.

Environmental Factors Affecting Outdoor Plants

Outdoor autoflowers must adapt to the surrounding environment. Weather patterns play a large role in how the plant grows during the first two weeks. Warm, sunny days often encourage faster growth, while cloudy or cool conditions can slow development.

Temperature changes between day and night can also affect the plant. Young cannabis plants prefer stable warmth. If nighttime temperatures drop too low, growth may slow for several days. This does not always mean the plant is unhealthy, but it does affect the speed of development.

Wind is another environmental factor that outdoor plants must handle. A light breeze can strengthen the stem and help the plant build structure. However, strong wind can stress a young plant. At only two weeks old, the stem is still thin, and heavy wind may bend the plant or damage delicate leaves.

Rainfall can also influence growth. While water is necessary, heavy rain can oversaturate soil and reduce oxygen around the roots. If the soil remains too wet, the plant may grow more slowly until the root zone dries and stabilizes again.

Light Variability and Its Impact on Growth

Light is one of the most important factors affecting plant development. Indoor growers use artificial lights, which makes it easier to maintain a steady lighting schedule. Autoflowers indoors often receive 18 to 20 hours of light each day. This stable light exposure helps the plant develop a compact structure and consistent leaf growth.

At day 14, indoor plants often have tight node spacing. This means the leaves and branches grow close together, creating a short and sturdy plant. When light intensity is correct and positioned at the proper distance, the plant grows efficiently without stretching.

Outdoor plants rely on sunlight. Natural sunlight is very powerful, but it is not always consistent. Cloudy weather can reduce light intensity, which may slow early growth. If the plant receives limited direct sunlight, it may stretch upward as it tries to reach stronger light. This can create taller plants with longer spaces between nodes.

This stretching does not always mean the plant is unhealthy. It simply shows that the plant is adjusting to the light it receives. As long as new leaves continue to appear and remain green, the plant is usually developing normally.

Soil Versus Container Growing Conditions

Indoor autoflowers are commonly grown in containers using soil or coco-based growing mediums. Containers allow growers to control watering and nutrient levels more precisely. At day 14, this control can help prevent common early problems such as overwatering or poor drainage.

The grower can also monitor the soil moisture more closely. This helps maintain the balance of water and oxygen that young roots need. Healthy root development during week two supports stronger plant growth later.

Outdoor plants may grow in containers or directly in the ground. When planted in the ground, roots have the potential to expand widely as the plant grows. However, soil quality becomes very important. If the soil is compact, poorly drained, or low in nutrients, early plant development may slow.

Outdoor container growing offers more control than ground planting, but weather conditions still affect the plant. Rain, temperature changes, and natural soil organisms all influence the environment around the roots.

Monitoring Plant Health in Different Growing Environments

Whether the plant grows indoors or outdoors, monitoring plant health is essential during the second week. At this stage, growers should look for signs of steady growth. Healthy plants usually produce new leaves regularly, and the leaves should appear green and well-formed.

Indoor plants may appear more consistent because the environment is stable. Growers can quickly adjust lights, temperature, or watering if something changes. This often helps correct small problems before they become serious.

Outdoor plants require closer observation because environmental conditions change more frequently. Growers should watch for signs of stress caused by weather, pests, or soil conditions. Small insects or sudden temperature drops can affect young plants more than mature ones.

Even if an outdoor plant grows slightly slower, steady development is still a positive sign. As long as the stem remains firm, leaves stay green, and new growth appears, the plant is usually healthy.

Indoor and outdoor autoflowers often look different at day 14 because the growing environments are very different. Indoor plants usually develop with more uniform structure due to controlled light, temperature, and watering. Outdoor plants experience natural conditions such as sunlight variation, wind, and changing temperatures, which can lead to more variation in growth.

Despite these differences, both indoor and outdoor plants can grow well when basic needs are met. Healthy leaves, steady growth, and a stable root system are the most important indicators of success during the second week. When growers maintain proper care and observe their plants closely, autoflowers can continue developing strongly as they move into later vegetative growth.

Signs Your Autoflower Is Healthy at 14 Days

At 14 days old, an autoflower is still very young, but it should already show clear signs of healthy growth. This stage matters because the plant is building its roots, stem, and leaves before it moves deeper into the vegetative phase. A healthy start often leads to better growth later. While every strain grows at its own pace, most healthy autoflowers at week 2 share the same basic traits. These include a strong stem, green leaves, steady growth, good node spacing, and a balanced shape.

Strong Stem Structure

One of the first signs of a healthy 14 day old autoflower is a firm and upright stem. The stem should be able to hold the plant up without leaning too much or falling over. It may still look small, but it should not appear weak, thin, or soft. A good stem is usually light green and looks clean, with no dark spots, pinching, or signs of damage.

At this age, the stem is still developing, so it does not need to be thick like an older plant. Still, it should show enough strength to support the first few sets of true leaves. If the stem looks long and very thin, the plant may be stretching for light. This often happens when the grow light is too far away or too weak. A stretched seedling can become unstable and may not grow as well later.

A healthy stem also shows that the root zone is doing its job. Roots take in water and nutrients, and that support helps the stem grow stronger. If the growing medium stays too wet for too long, the roots may struggle, and the stem may stay weak. Good airflow can also help. A gentle movement of air around the plant can encourage the stem to become stronger over time.

Bright Green Leaf Color

Leaf color is one of the easiest ways to judge plant health at week 2. A healthy autoflower usually has leaves that are bright to medium green. The color should look even across the plant. The leaves should not look pale, yellow, or blotchy. They also should not have brown tips, rusty spots, or dark burnt edges.

Green leaves show that the plant is making chlorophyll and using light well. This is important because chlorophyll helps the plant turn light into energy. At 14 days, the first true leaves and newer growth should both look fresh and alive. Very dark green leaves can sometimes mean too much nitrogen, while very light green leaves may point to weak feeding, poor root health, or watering problems.

The texture of the leaves matters too. Healthy leaves should look smooth and open. They should not be drooping heavily, curling under, or twisting in a strange way. A little variation is normal, but the plant should still look comfortable in its environment. If the leaves are praying slightly upward toward the light, that can often be a good sign that the plant is responding well to its conditions.

Steady Daily Growth

A healthy 14 day old autoflower should show steady growth from day to day. The change may not be huge each day, but the plant should slowly get bigger. New leaves should keep forming from the center. The stem should grow a little taller, and the leaf sets should begin to spread out more.

Autoflowers grow on a limited timeline, so steady progress matters. These plants do not have as much recovery time as photoperiod plants. That is why healthy early growth is so important. By the end of the second week, many autoflowers have moved past the very early seedling stage and are entering early vegetative growth. If the plant looks the same size for many days in a row, that may be a sign of stress.

Growth speed can vary by strain, container size, temperature, light level, and root health. Even so, a healthy plant should not look stuck. New growth should appear clean, green, and slightly larger than the older leaves. When growers check their plant each day, they should be able to notice small signs of forward movement.

Proper Spacing Between Nodes

Node spacing is another helpful sign of good health. Nodes are the points on the stem where leaves and branches grow. At 14 days, a healthy autoflower should have a compact but not crowded structure. The spaces between nodes should be short enough to show the plant is getting enough light, but not so tight that the leaves pile on top of each other.

If the space between nodes is too wide, the plant may be stretching because it wants more light. This can lead to a tall, weak plant with less support. If the nodes are very tight and the leaves seem packed together, the light may be very intense, or the plant may simply have a naturally compact structure. In many cases, short and even node spacing is a sign that the environment is balanced.

Proper node spacing also helps later growth. It gives the plant a solid frame for future branches, leaves, and flowers. At this stage, growers want to see a young plant that is building a stable shape rather than growing too tall too fast.

Balanced Plant Shape and Leaf Formation

A healthy autoflower at day 14 should have a balanced overall shape. This means the plant looks even, upright, and well formed. The leaves should spread out around the stem in a natural way. One side should not look much larger or weaker than the other. The newest growth at the top should look centered and active.

Leaf formation should also look normal for the stage. By week 2, the plant should have several sets of true leaves, and each new set should look larger and more developed than the one before it. The leaf fingers should be shaped clearly, and the plant should not look misshapen or damaged. Minor differences can happen, but the general pattern should still look healthy and organized.

A balanced plant shape often means that the light is placed well, the watering is under control, and the roots have enough room to grow. It also shows that the plant is not under major stress from heat, cold, pests, or nutrient issues. Healthy young plants usually have a simple, clean look. They do not appear messy, limp, or uneven.

A healthy 14 day old autoflower may still be small, but it should show strong early signs of success. The stem should be firm and upright. The leaves should be bright green and open. The plant should keep growing a little each day. The spacing between nodes should look even, and the overall shape should appear balanced and natural.

Conclusion: What to Expect After the 14 Day Autoflower Stage

By the time an autoflower reaches day 14, it is still very young, but this stage tells you a lot about how the plant is doing. The first two weeks are all about building a strong base. At this point, the plant should no longer look like a tiny new seedling. It should be moving into early vegetative growth. That means you should start to see more leaf sets, a thicker stem, and more steady upward growth. The plant may still be small, but healthy growth matters more than size alone.

A normal 14 day old autoflower often looks short, compact, and fresh green. The leaves should look open and firm, not weak or droopy. The stem should be standing upright and should look a little stronger than it did during the first week. You may also notice that the plant starts to grow faster after this point. Many growers worry when their autoflower seems small at day 14, but not every plant grows at the same rate. Genetics, light, temperature, watering habits, and root health all affect how large the plant becomes in the first two weeks.

What matters most is whether the plant looks healthy and keeps improving day by day. A healthy autoflower at this stage usually has even leaf growth, a good green color, and no major signs of stress. The leaves should not be badly twisted, burned, yellow, or curling down. The growth from the center of the plant should look active. New leaves should keep appearing, and the plant should look alive and balanced. The space between nodes should not be too wide, because wide spacing can suggest weak light. At the same time, the plant should not look too cramped, pale, or stalled.

The care you give at this stage can shape the rest of the plant’s life. Autoflowers grow on a fixed timeline, so they do not have as much recovery time as photoperiod plants. If a young autoflower becomes stressed in week two, it may stay smaller later on. This is why stable conditions matter so much. Good light, careful watering, proper temperature, and a healthy root zone are all important right now. Overwatering is still one of the most common mistakes at this age. When the growing medium stays too wet, roots get less oxygen, and growth can slow down. On the other hand, when the plant gets the right amount of water and enough air around the roots, it can move into faster growth with less stress.

Nutrition also becomes more important after day 14. Some plants may still be feeding mostly from the growing medium, while others may be ready for light nutrients, depending on the setup. The key is to avoid doing too much too soon. Young autoflowers do not usually need heavy feeding early on. Too much fertilizer can burn the plant and slow it down. A gentle approach is usually safer. If the leaves are healthy and green, that is often a sign that the plant is getting what it needs. If problems appear, such as pale leaves or rusty spots, growers should look at the full picture before adding more nutrients. Light strength, pH, root health, and watering habits can all affect how nutrients are used.

After the 14 day mark, many autoflowers enter a stronger period of vegetative growth. During weeks three and four, the plant often grows faster, gets wider, and forms more nodes. The stem becomes stronger, and side growth may begin to spread out more. This is the stage where the plant starts building the structure that will support future buds. A healthy plant will usually look more vigorous during this time. You may notice faster daily changes, especially if the environment stays stable. Leaves may get larger, the canopy may start to fill out, and the plant may begin to look more mature overall.

This next phase is also when growers need to stay observant. Problems that begin in week two can become more obvious in week three. A plant that is too wet, underfed, overfed, or light-stressed may stop progressing as expected. That is why it helps to check the plant closely each day. Look at leaf color, leaf shape, stem strength, and overall growth speed. You do not need to overreact to every small change, but you do need to pay attention. Small problems are easier to fix when caught early.

As the plant moves beyond day 14, the goal is to keep conditions as even as possible. Sudden changes in temperature, humidity, light distance, or feeding can create stress. Autoflowers usually respond best to a steady routine. Keep the plant in a comfortable environment, water only when needed, and avoid unnecessary handling. If training is planned, it should be done with care and only when the plant looks healthy enough to handle it. Even then, gentle methods are usually the better choice.

The 14 day stage is not the finish line. It is the point where early care starts to show results. A plant that looks healthy now has a much better chance of growing well in the weeks ahead. Strong roots, healthy leaves, and steady growth at this age often lead to a better structure later in life. That structure matters because it affects how well the plant can support flowers, take in light, and use water and nutrients.

In simple terms, a 14 day old autoflower should look young but strong. It should not need to be perfect, but it should show clear signs of healthy progress. After this stage, expect faster vegetative growth, more leaves, more structure, and a greater need for consistent care. When week two goes well, the plant is in a much better position to handle the rest of its short life cycle. Good early care does not guarantee a huge harvest, but it gives the plant its best chance to grow into a healthy and productive autoflower.

Questions and Answers

Q1: What should a 14 day old autoflower look like?
A healthy 14 day old autoflower should have several sets of true leaves and a small but sturdy stem. Most plants at this stage are about 2 to 5 inches tall and usually have 3 to 4 nodes. The leaves should appear green and healthy.

Q2: How tall should a 14 day old autoflower be?
Most 14 day old autoflower plants are between 2 and 5 inches tall. The exact height depends on the strain, lighting, and growing conditions. Some compact strains remain shorter while others stretch slightly more.

Q3: How many nodes should a 14 day old autoflower have?
A healthy 14 day old autoflower typically has around 3 to 4 nodes. Nodes are the points where leaves and branches grow from the stem. If there are fewer nodes, the plant may be experiencing slow growth.

Q4: Should a 14 day old autoflower be given nutrients?
Some growers begin light feeding around day 14 because the plant starts growing faster. Nutrients should be mild and designed for early vegetative growth. Too much fertilizer can damage young roots.

Q5: How often should you water a 14 day old autoflower?
A 14 day old autoflower should be watered when the top layer of soil becomes dry. Overwatering is common at this stage because the roots are still small. Controlled watering helps the roots grow stronger.

Q6: Can you start training a 14 day old autoflower?
Light low stress training may begin around day 14 if the plant looks strong and healthy. This method involves gently bending the stem to encourage more side branches. Heavy training techniques should be avoided.

Q7: What light schedule is best for a 14 day old autoflower?
Autoflowers usually grow well under 18 to 20 hours of light per day during early growth. This schedule provides enough energy for development. Unlike photoperiod plants, autoflowers do not require light cycle changes to start flowering.

Q8: Why is my 14 day old autoflower growing slowly?
Slow growth can happen due to weak lighting, poor soil, incorrect watering, or low temperatures. Autoflowers grow faster when the environment remains stable and warm. Adjusting these factors often improves growth.

Q9: What temperature and humidity are best for a 14 day old autoflower?
Temperatures between 70°F and 80°F with humidity around 55% to 65% are usually ideal. These conditions help the plant absorb water and nutrients efficiently. Extreme heat or dry air can slow development.

Q10: When will a 14 day old autoflower start flowering?
Most autoflower plants begin flowering around week 3 or week 4 after germination. A 14 day old plant is still in the early vegetative stage. Soon after this stage, small pre-flowers start to appear.
