When growing cannabis, seeing brown pistils four weeks into flowering can be alarming for any grower. Pistils are the hair-like structures that protrude from the buds and play a crucial role in the reproduction of the plant.
They are usually white or light-colored during the early stages of flowering, and their color changes as the plant matures. However, if you notice Pistils Turning Brown 4 Weeks Into Flowering, it could be a sign that something is wrong.
Understanding pistils and their role in flowering is essential to diagnose the problem. Pistils are the female reproductive organs of the cannabis plant, and they play a crucial role in the pollination process. When a male plant releases pollen, it fertilizes the female pistils, resulting in the production of seeds.
However, most growers prefer to grow seedless buds, also known as sinsemilla, by preventing pollination. In this case, the pistils’ role is to capture pollen from the air and prevent it from reaching the buds.
Several factors can cause pistils to turn brown prematurely, including nutrient deficiencies or excesses, watering issues, plant stress, and pollination. Identifying the underlying cause is crucial to prevent further damage to the plant and ensure a successful harvest.
In this article, we will explore the possible causes of brown pistils four weeks into flowering and provide tips on how to deal with them.

Understanding Pistils and Their Role in Flowering
The Function of Pistils
Pistils are a vital part of the female cannabis plant’s reproductive system. They are the female reproductive organs that are responsible for receiving pollen from male plants. When a pistil is pollinated, it will produce seeds, which are used to create new cannabis plants.
During the flowering stage, pistils begin to emerge from the bud site. They start out as white hairs and gradually turn brown as the plant matures. Brown pistils are a sign that the plant is nearing the end of its flowering cycle.
Stages of Pistil Development
There are three main stages of pistil development:
- Emergence: During this stage, pistils begin to emerge from the bud site. They are small and white and have a hair-like appearance.
- Growth: As the plant continues to mature, the pistils will grow longer and thicker. They will also start to change color, turning from white to orange and finally to brown.
- Maturity: When the pistils have turned brown and started to curl in on themselves, it is a sign that the plant is mature and ready to be harvested.
It is important to monitor the color of the pistils during the flowering stage to determine the optimal time to harvest the plant. Harvesting too early can result in a lower yield, while harvesting too late can result in a decrease in potency.
Why Pistils Turn Brown
When pistils turn brown, it can be a sign of various factors. In this section, we will discuss some of the most common reasons why pistils turn brown during the flowering stage.
1. Environmental Factors
The environment in which the plant is grown can play a significant role in the color of the pistils. If the plant is exposed to cold temperatures, the pistils can turn brown due to frost damage. Similarly, if the plant is exposed to high levels of pollution or chemicals, the pistils can turn brown due to environmental stress.
2. Lighting Conditions
Lighting conditions can also affect the color of the pistils. If the plant is exposed to too much light, the pistils can turn brown due to light burn. On the other hand, if the plant is not exposed to enough light, the pistils can turn brown due to lack of light.
3. Heat and Humidity
Heat and humidity can also affect the color of the pistils. If the plant is exposed to high levels of heat and humidity, the pistils can turn brown due to heat stress. On the other hand, if the plant is exposed to low levels of humidity, the pistils can turn brown due to dehydration.
Impact of Nutrients and Watering
Importance of pH Balance
One of the most important factors for healthy plant growth is maintaining the correct pH balance in the soil. If the pH level is too high or too low, the plant will have difficulty absorbing nutrients, which can lead to a number of problems, including brown pistils. Ideally, the pH level should be between 6.0 and 7.0 for cannabis plants.
Proper Watering Techniques
Proper watering techniques are also essential for healthy plant growth and avoiding brown pistils. Overwatering can lead to root rot and nutrient deficiencies, while underwatering can cause the plant to become stressed and produce less resin. It is recommended to water the plant when the top inch of soil feels dry to the touch.
Role of Nutrients
Nutrients are essential for plant growth, but too much or too little of certain nutrients can cause brown pistils. It is important to provide the plant with a balanced diet of macronutrients (such as nitrogen, phosphorus, and potassium) and micronutrients (such as calcium, magnesium, and iron).
It is also important to monitor the plant’s ppm levels to ensure that it is not being overfed or underfed.
When it comes to nutrients, it is important to use high-quality products that are specifically designed for cannabis plants. It is also important to follow the manufacturer’s instructions for use and to avoid overfeeding the plant. Overfeeding can cause nutrient burn, which can lead to brown pistils and other problems.
Signs of Plant Stress and Pollination
When pistils start turning brown at week 4 of flowering, it can be a sign of plant stress or pollination. Here are some things to look out for:
Identifying Hermaphrodite Plants
One possible cause of brown pistils is the presence of hermaphrodite plants. Hermaphrodite plants have both male and female reproductive organs, which can lead to self-pollination and the development of male flowers.
This can cause the pistils to turn brown and the buds to stop growing. To identify hermaphrodite plants, look for small balls or sacs that resemble male flowers. These can be found on the same plant as the female flowers.
Understanding Pollination Process
Another possible cause of brown pistils is pollination. When a female plant is pollinated, it will start to produce seeds. This can cause the pistils to turn brown and the buds to stop growing.
Pollination can occur naturally through wind, insects, or other means. It can also be caused by a nearby male plant or fan blowing pollen onto the female plant.
To prevent pollination, it is important to remove any male plants from the grow area. It is also important to keep the grow area free of pollen. This can be done by using a HEPA filter or by keeping the grow area sealed off from the outside environment.
In conclusion, brown pistils at week 4 of flowering can be a sign of plant stress or pollination. To prevent these issues, it is important to identify hermaphrodite plants and understand the pollination process. By taking these steps, growers can ensure that their plants stay healthy and produce high-quality buds.
Dealing with Pests and Diseases
Common Pests
Pests can be a significant problem during the flowering phase. Some of the common pests that can affect pistils include spider mites, thrips, and aphids. These pests can cause damage to the pistils, leading to browning and other issues.
Spider mites are tiny pests that can cause significant damage to the plant. They feed on the sap of the plant, which can cause the leaves to wilt and turn yellow. They can also damage the pistils, leading to browning. Thrips are another common pest that can affect pistils.
They feed on the plant’s sap, which can cause the leaves to curl and turn brown. They can also damage the pistils, leading to browning. Aphids are another common pest that can affect pistils. They feed on the sap of the plant, which can cause the leaves to curl and turn yellow. They can also damage the pistils, leading to browning.
Preventive Measures
Preventing pests is essential during the flowering phase. Some of the preventive measures that can be taken include maintaining proper hygiene, using organic pesticides, and avoiding over-fertilization.
Maintaining proper hygiene is critical during the flowering phase. Keeping the grow area clean and free of debris can help prevent pests from taking hold. Using organic pesticides can also be an effective way to prevent pests. These pesticides are less harmful to the plant and the environment than chemical pesticides.
Over-fertilization can also be a problem during the flowering phase. Too much fertilizer can lead to nutrient burn, which can cause the leaves to turn brown and the pistils to become damaged. It is essential to follow the manufacturer’s instructions when fertilizing the plant and to avoid over-fertilization.
Monitoring Bud Growth and Pistil Health
When growing cannabis, it is important to monitor the health of the buds and pistils to ensure a successful harvest. Here are some tips on how to observe and track bud growth and pistil health during the flowering stage.
Observing Trichomes
Trichomes are tiny, hair-like structures that cover the buds and leaves of cannabis plants. They are responsible for producing the resin that contains the cannabinoids and terpenes that give cannabis its unique effects and flavors.
As buds mature, the trichomes change color and shape, which can help growers determine when to harvest.
To observe trichomes, use a magnifying glass or microscope to get a closer look. As the buds mature, the trichomes will change from clear to cloudy, and eventually to amber.
Clear trichomes indicate that the buds are not yet ready for harvest, while cloudy trichomes indicate that the buds are at their peak potency. Amber trichomes indicate that the buds are past their peak and may have a more sedative effect.
Tracking Pistil Changes
Pistils, also known as “hairs,” are the tiny, white structures that emerge from the buds during the flowering stage. They play an important role in reproduction, but can also help growers determine when to harvest. As the buds mature, the pistils will change color and shape.
At the beginning of the flowering stage, the pistils will be white and stick straight out from the buds. As the buds mature, the pistils will begin to curl inwards and change color.
Brown or red pistils indicate that the buds are maturing and will be ready for harvest soon. However, if the pistils are turning brown too early, it could indicate a problem with the plant’s health or growing conditions.
It is important to track the changes in pistil color and shape to determine the optimal time for harvest. Keep a close eye on the pistils and take pictures to compare with previous weeks. Additionally, monitor the health of the leaves, as new ones should be growing and the tips should not be turning brown.
