How to detect nitrogen deficiencies and how to correct them?

Written by on 3 October, 2020

While it is true that cannabis plants need various nutrients for proper growth, such as potassium, phosphorus and nitrogen (to name a few), in this opportunity we will focus on talking about the latter, ie, nitrogen, specifically, how to detect deficiencies of this nutrient and how to correct that situation.

Nitrogen: a necessary element

The nitrogen is an element very necessary for the development of the plants of cannabis, since it exerts a fundamental role in the production of chlorophyll, amino acids, and proteins among others. This nutrient is the main responsible for the growth of the stem, leaves, branches and vigor in general.

Nitrogen deficiencies

Nitrogen deficiency in marijuana plantations is often one of the most common problems faced by cannabis growers. It is therefore very important that you are aware of your growing, so that you can detect deficiencies in time, if they occur.

However, how you can realize the lack of nitrogen, well fortunately, the plants of cannabis give you certain indications. These are some of the symptoms:

– The plants have a slow growth and development, and they will be weak.

– Mainly, the leaves of the cannabis begin to become yellow. First the lower leaves do, and then it advances to the upper ones.

The discoloration on the leaves begins to be perceived in the tips, which also tend to become brown. Finally, the leaf dries and dies.

– The stems of the plants may look reddish.

– The plants have less defense against pests, diseases, among other symptoms.

How you can solve a nitrogen defiency?

One of the things you can do to correct this deficiency is to add a nitrogen-rich fertilizer to the nutrient solution. However, be careful not to overdo it with this element, as it can be counterproductive. When there is an excess of nitrogen, cannabis plants do not develop properly either.

Use the dose of nitrogen according to the stage of life in which your plant is, remember also that the varieties of cannabis are different, therefore, will require specific doses.

In addition, the type of nitrogen with which you feed your plant will depend on the method of growing you are using.

Recommendation

Be sure, identify the causes for which your cannabis plant manifests these symptoms, since they can be confused with the symptoms that are presented by the lack of other nutrients, and in turn, these can occur for other reasons. That is why it is important to verify the causes, to avoid making mistakes.

On the other hand, try to keep factors such as pH, among others, at the appropriate levels, to avoid the lack of nitrogen and other nutrients.
