Why is My Weed Plant Yellow? Explained!

If you’re growing a weed plant, you might be wondering why it’s yellow. It can be caused by a number of different things, but there are some steps you can take to help find out what’s causing it.

Nitrogen deficiency

If you have a marijuana plant that’s beginning to turn yellow, it may be because of nitrogen deficiency. Although this condition is common, it can seriously affect the plant’s health. It can also make a big difference in the way the harvest turns out.

Nitrogen is one of the most important macronutrients in the plant’s diet. It is a mobile element, which means that it can move from the bottom of the plant to the top. This movement occurs throughout the plant, but it’s most likely to occur in the lower leaves.

Nitrogen is present in almost all plant foods. However, it can be easily stolen by other elements. When this happens, the leaves of the plant will begin to turn yellow and curl. In extreme cases, the leaves may even be black.

To prevent nitrogen deficiency, the best solution is to feed the plants with high-nitrogen fertilizers. These fertilizers can quickly and effectively deliver nitrogen to the roots of the plant. You can buy a growth fertilizer from any nursery. The high-nitrogen concentrations can help the plant bounce back from the condition.

Symptoms of nitrogen deficiency in cannabis are easy to recognize. They can be caused by a number of factors, including bad soil or organic matter. Plants that are starving tend to be more susceptible to insects and diseases.

Leaves that turn yellow because of nitrogen deficiency are usually found in the lower leaves. Lower leaves are the first to die. Newer leaves take up the nitrogen from the older leaves and replace them.

When nitrogen deficiency is not treated, the leaves may begin to fall off the plant on their own. In addition, the plant will reduce its branches and flowers.

If your marijuana plant is experiencing nitrogen deficiency, it’s important to correct the situation before it spreads. Using a growth fertilizer is the best option. You can find a high-nitrogen water-soluble growth fertilizer in any nursery.

Besides using a high-nitrogen fertilizer, you can also use a natural nitrogen fix. If you add a little bit of this to your grow medium, the plants can recover from the condition.

Over- or underwatering

If you’ve been growing marijuana for a while you’re probably already aware that yellowing is a common problem. Thankfully, the symptoms can be easily reversed. But, before you can make that happen, you need to know what causes the yellowing of weed plants.

Overwatering is the most common cause of yellowing. You should water your plants every two to three days, but you should not let the growing medium dry out entirely. Water is essential to the growth of cannabis, but overdoing it can have negative consequences.

Using a soil moisture meter is a good way to make sure you’re not watering your plant too much. Another good indicator is if your soil looks dry under the pot.

Yellowing of marijuana leaves are a sign of several problems, but nutrient deficiency is the most common. To remedy this problem, you’ll need to do a little research.

There are a few more things you should do to get your cannabis plant to its full potential. The most obvious is to use a good quality water source. Also, you should check the temperature. Keep the room cool at night, but not too cold during the day.

Using a high-quality grow light can also help, but you should make sure it’s at the right height. As long as you have the right amount of light, the rest should be easy.

If you’re not ready to invest in a grow light, you can check your plant’s growth by lifting the pot. A few taps on your finger will tell you if the substrate is too moist or too dry.

The most important thing you can do is to find the source of the problem. If you haven’t been able to determine the problem, you might be better off just pulling the weed. Otherwise, you can try pruning the offending foliage. This will not only reduce the amount of damage to your plant, but it will also help you identify the cause of the problem.

For seasoned cannabis cultivators, there are probably many more possible causes of your plant’s yellowing than we’ve mentioned here. Remember, the more you know about your plant, the more likely you’ll be able to prevent serious damage before it occurs.


When it comes to cannabis, the temperature is often the culprit. If you are growing indoors, you will likely need to raise the thermostat a few notches to avoid having your buds turn into a pale orange mush. On the other hand, if you have an outdoor garden, you may need to enclose your budtenders to avoid freezing. To keep the cool air flowing, you might even consider covering your plants, or at least keeping the lights on.

The best way to keep your budtenders happy is to provide them with the proper amount of light, especially in the early stages. It is also important to ensure that the humidity is up to snuff, as plants will often dry out more rapidly than you would like. As for temperature, it is a good idea to set up a DIY greenhouse to prevent losing leaves to the elements.

A properly functioning light and air circulator is the key to keeping your plant’s humidity in check. There are many other factors that play into the budtenders’ overall health, but the temperature is the least of their worries. While you may be tempted to enclose your plants in plastic wrap, it is advisable to invest in a quality air conditioning unit. In the end, you’ll be rewarded with a more vibrant plant and a stout budtender.

While the temperature is a factor, you might want to consider the benefits of a cool night’s sleep. While you can’t exactly put your budtenders in a closet for a few hours of sleep, you can do a little DIY magic to keep the cool air flowing in your greenhouse, or even have them sleep under your roof if you have a large garden. You can even add a couple of extra fans to the mix for added coolness, and even a sprinkler system to bring the stale air out. With a little extra planning and preparation, you’ll have a happy, healthy, and sexy plant that will be ready to harvest in no time. Having said that, remember that budtenders are people too, so you need to be prepared for a few bumps in the road.

Fungus gnats

If you have just noticed your cannabis plant has turned yellow, you probably aren’t sure what’s causing it. It can be a sign of an infestation or something you can simply treat.

If you are unsure, you can take a look at the lower leaves. These tend to turn yellow in the end stages of the flowering process. The leaves at the bottom of the plant are not using energy efficiently. You can also check the top of the plant to see if there are any pests on it.

If your cannabis plant has turned yellow, it might be due to a nutrient deficiency. Nutrient deficiencies can occur when the plant gets too much or too little of certain nutrients. For example, iron deficiencies only affect the newest leaves.

Alternatively, your plant could be suffering from a fungus gnat infestation. Fungus gnats lay their eggs in the soil and are often drawn to the plant’s leaves. When these insects feed on the plant, the leaves will start to yellow.

Another problem that can cause your cannabis plant to turn yellow is an infestation by spider mites. Spider mites can be removed from the plant by pruning them or applying aromatic oils. In addition, if your weed is in an indoor crop, you should apply organic pesticides to keep them from spreading.

If your plant is in a greenhouse, you can also check the temperature. During prolonged periods of high temperatures, it can cause the plant to produce odd symptoms.

Some people are not happy about the color of their weed, especially if it’s yellow. However, this is not a sign of bud rot. Instead, the leaves are undergoing a natural senescence process.

So, if you’ve found out that your weed has turned yellow, it’s important to get it treated as soon as possible. A yellow marijuana plant can be easily fixed, but quick action is crucial to avoid damage to the plant. As long as you follow the instructions for treating the problem, your weed will be back to its full health in no time.
