Cannabis Nitrogen Deficiency: What Is It & how To Fix the Problem?

Cannabis nitrogen deficiency: When you are growing a cannabis plant, you can’t neglect the important nutrients that are required for the proper growth and development of the plant. If you are noticing some changes in your plant, then it can be a cause of nitrogen deficiency. Just like every other nutrient, nitrogen is very helpful to plants of all types, including cannabis, and if your plant is not getting enough nitrogen from the soil or fertilizer you are providing, then you must pay attention immediately.

Here in this post, we have discussed everything about the nitrogen deficiency in cannabis plants and how you can fix this problem. Don’t worry if you are new to growing cannabis plants because we have covered every crucial information that can be helpful to you in growing your plant without any assistance.

Why Do Cannabis Plants Need Nitrogen?

As we have said above, nitrogen plays an important role in the growth and development of plants because it increases the production of chlorophyll compound, which is required for the photosynthesis process. Not only this but nitrogen also helps in forming various types of proteins and enzymes in the plant that directly influences the working of cell growth.

Cannabis Nitrogen Deficiency

If your plant lacks nitrogen, then the stems and leaves of your cannabis plant will stop growing. During the flowering stage, nitrogen is also needed to support the growth of buds, but it should be limited to prevent excessive growth of foliage. So, we hope you might have understood why your marijuana plant needs nitrogen.

Signs of Nitrogen Deficiency In Plants

Don’t worry if you are not a professional grower because the symptoms and signs will definitely tell you that your plant is lacking something. You will be able to notice visual changes in your plant, and by figuring out the signs, you can get to know the real reason behind them.

This is just another reason why you must keep a track record of the growth and development of the plants, as you will be able to notice the changes early and treat them before the problem gets serious. Below we have mentioned a few symptoms that your cannabis plant will show when there’s a deficiency of nitrogen, so you will be able to solve it without any issues.

Yellowing of Lower Leaves – The first signs of nitrogen deficiency are yellowing and browning of the lower leaves. As the deficiency progresses, the yellowing will spread to the rest of the plant. While other deficiencies will start from the upper leaves, the nitrogen deficiency will start from the lower part of the plant.

Stunted Growth – As we have already said above, nitrogen is essential for stem and leaf growth, so plants that are deficient in nitrogen will exhibit stunted growth. You might not notice it at first because the growth is generally slower, so we will recommend you check the colour of the leaves before jumping to a conclusion.

Reduced Yield – If your plant is already big and in the flowering stage, then the buds will not form. Also, if your plant already has some buds, then they might start shrinking and falling from the plant. The leaves and stems will not be able to support the formation of new buds because the overall immunity of the plant gets weakened.

Curling Leaves – If the leaves have started curling inwards or downwards, then it can be a symptom of nitrogen deficiency too. Though it is important to be sure before starting the treatment, so we will recommend you check a few other symptoms as well. If they match with this one, then it means your plant is lacking nitrogen.

Bugs & Insects – Since your plant is no longer good at the photosynthesis process, the entire functioning will collapse, including anti-disease processes. If you are noticing more insects and bugs on your plant, then it means there’s some problem with it. It can either be because of nitrogen or calcium, as deficiencies of these both can cause this issue.

How To Fix Nitrogen Deficiency In Marijuana Plants [GUIDE]

Outdoor plants can adjust the amount of nitrogen by consuming only the required, but if you are using a planter or growing cannabis indoors, then you will have to pay attention to the amount of nitrogen in the soil. Since we have told you everything about the signs and symptoms to look in your plants to be sure it is lacking nitrogen, you can start the treatment too.

There are always some working methods available to fix the problem with your plants, and the same goes for nitrogen deficiency in cannabis plants. Below we have shared some proven ways that you can follow to solve this problem without any assistance.

  • If soil pH is outside the optimal range for cannabis growth, adjust it to the correct range to improve nitrogen availability.
  • Providing the right amount of nitrogen in the form of a fertilizer works wonder. Not only nitrogen but fertilizers can fix most problems.
  • Flushing the soil with water can help remove excess salts that may reduce the availability of nitrogen and other nutrients to the plant.
  • Ensure that the light cycle is consistent and within the optimal range for cannabis growth, to improve the plant’s ability to absorb nitrogen.
  • Adjust the watering schedule to avoid overwatering, which can leach nitrogen from the soil. You can also consult a professional grower for some assistance.

Nitrogen Toxicity vs Nitrogen Deficiency In Plants

Nitrogen Toxicity – As we all know, too much of something is bad, and the same goes for nitrogen. If your plant is getting more than the required amount of nitrogen, then it will fall under nitrogen toxicity. Soil pH imbalances can also cause nitrogen toxicity, as the plant’s ability to absorb nitrogen is affected when soil pH is too high or low.

All the signs and symptoms we have mentioned above in this post belong to nitrogen toxicity, too, so always check the plant. Always ensure that your plants are receiving the right amount of nutrients, water, light, and wind conditions, or else they will not grow properly, and in some rare cases, they might die too.

Nitrogen Deficiency – If you want to get the best quality buds and growth of your cannabis plants, then you must ensure there’s everything in the right amount. However, deficiency of nitrogen in cannabis plants is a very rare case because it comes under the micronutrient category that is required in very small quantities by the plant.

For indoor growers, it is essential because everything is provided to the plant manually, and they often face this problem. Organic matter, such as compost or manure, can also be added to the soil to provide the plants with the necessary nitrogen. This method is especially effective if the soil is poor in organic matter.

FAQs Related To Cannabis Nitrogen Deficiency

What Are Early Signs of Nitrogen Deficiency?

The earliest signs of nitrogen deficiency depend on various factors. For example, if your plant is in the flowering stage, then the buds will start shrinking, and no new buds will form. If your plant is in the growing stage, then you will notice that the leaves have started turning yellow and the stem has become weaker.

Is Overwatering The Same As Nitrogen Deficiency?

Overwatering can cause root rot and restrict the plant’s ability to absorb water and nutrients, but it does not cause a deficiency of nitrogen specifically. Both overwatering and nitrogen deficiency can lead to decreased yields and reduced quality of the final product, but they are caused by different factors and require different solutions.

Can Cannabis Recover From Nitrogen Deficiency?

Yes, your cannabis plant can possibly recover from nitrogen and other deficiencies, but only if you take action on time. This is just another reason why everyone suggests maintaining a proper track of the growth and development of the plant. This helps you identify the problem early so you can start the cure.

How Do Plants Look When It Is Lacking Nitrogen?

If you notice that the leaves are turning yellow, the yield of the plant has shrunk, and there’s no further growth of the plant, then you can assume your plant is lacking nitrogen. Also, to conserve energy, the plant will turn its foliage a dark green color. However, it is important to ensure it by checking the pH level of the soil.

How Can I Add Nitrogen Quickly?

One of the easiest ways to add nitrogen to your plants is by using a liquid or a slow-release granular fertilizer that is rich in nitrogen. You can also add coffee grounds to the soil as they are a very rich source of nitrogen. Some other proven solutions include blood meal, ammonium sulfate, and compost.

Final Words

So, this is all about cannabis nitrogen deficiency, and we hope now you know everything about it, and you are able to fix it on your own. The deficiency symptoms depend on various factors, as we have said above, and you must apply the fix according to the symptom.
