In today’s post we are going to talk to you about a problem that usually occurs to our growers, the lack of calcium and magnesium in the marijuana plant.
It is a very common problem among growers, whether you are a novice or professional grower. We are going to tell you how to solve this deficiency, which can lead to two different elements, and its symptoms may appear at the same time or be confused in the initial stages.
How do we identify calcium deficiency in plants?
In the growing season where the roots need and consume a lot of nutrients and the plant solar radiation, it develops quickly. Given the lack of calcium and magnesium in this growth phase, we will see some yellow-brown spots on the leaves.
In addition, the growth process will be reduced, the plant grows slower and the stems will begin to take on a purple color during the flowering phase.
This is due to the deficiencies of nutrients and elements, but we have to know how to differentiate that sickly appearance that is due.
Let’s say that you have to know how to differentiate between micronutrients and secondary macronutrients such as Calcium and Magnesium.
Benefits of Calcium and Magnesium in the marijuana plant
They are two fundamental secondary macronutrients for marijuana to grow vigorously and have excellent plant and reproductive development.
First let’s talk about the benefits of calcium:
The plant will not be able to develop its cell walls correctly and therefore its cell structure, in addition to being able to maintain its vital signs in the correct state.
It will improve growth and flowering, as it has a more solid and strong structure.
Plants need calcium to be able to grow, develop roots, leaves, stems and flowers, it also benefits their defense system, to protect themselves from external threats.
The root system also benefits from calcium, since it facilitates the degradation and decomposition of organic nutrients, so that the plant can absorb and assimilate them.
It helps regulate its temperature and exchange gases, among other benefits.
Now it’s time to talk about the benefits of magnesium:
One of the basic elements for the creation and production of chlorophyll. With it, photosynthesis is carried out, a fundamental process in the life of plants, where the sunlight that it absorbs through this process converts it into chemical energy in the form of sugars.
It also influences the activation of enzymes and the creation and transport of sugars inside the plant.
The yellow-brown spots that appear on the leaves of marijuana, which we discussed in the previous point, are due to a lack of magnesium, among other components.
Solve calcium and magnesium deficiency in marijuana
If a plant cannot develop its cellular structure correctly, does not breathe well and cannot absorb light properly, it will not develop its constants and it loses vital force.
For these reasons, maintaining a good level of nutrients such as calcium and magnesium can help us save the cultivation of marijuana or cannabis.
VegetalBioplant, aware of this problem, has created the organic product to control this deficiency, calcium and magnesium fertilizer for marijuana, made by our laboratory, 100% organic.
To find out how much you have to supply to the plant, you can visit the irrigation tables in our online premium fertilizer store.
Being responsible with the doses you supply to the plant can avoid an overdose, a lack is just as bad as an excess.
How to identify an excess of Calcium or Magnesium?
The excess is difficult to detect, it is characterized by blocking several macronutrients such as potassium, magnesium, manganese and iron. Given this lack of nutrients, the plant will have difficulty breathing.
Identifying these deficiencies and correcting these types of problems is the difference between being an expert grower or a beginner.
Due to our years of experience, we know that excess calcium occurs at the tips of marijuana leaves, where small black dots will appear or have been burned.
Solution of excess calcium in marijuana plants
The most important thing to solve the excess calcium is to wash the roots of our plant very well and we also recommend changing the pot if it is a normal crop.
If the crop is hydroponic, when there is an excess of calcium in the water tank, it comes into contact with the sulfur and will precipitate to the bottom of the tank, in this case we will have to change all the water, clean it and adapt it again to the needs of the crop.
In this way, we will get the marijuana plant to grow again as expected and not indiscriminately as it was doing due to excess calcium.
