The Secondary Nutrients for Cannabis

the secondary nutrients of cannabis

In growing Cannabis, nutrients play an important role in its overall development and growth. Nutrients are the food of your Cannabis, just like other plants, without enough nutrients, your weeds will starve and it will result in possible damage.  There are main nutrients for Cannabis growing; these are N-P-K or the nitrogen, phosphorous and potassium. These elements are considered as the basic food in growing weeds. However, the presence of secondary elements in weed growing is also vital. Although they are just secondary, they are important as the basic elements in growing pot.

When we refer to secondary elements of Cannabis, these are the additional nutrients our Cannabis needs in order to grow healthy and produce potent buds. So what are these secondary nutrients? These are the following:

1)    Calcium

Calcium may be underestimated because it is just a secondary nutrient. However, you need to know the fact that calcium is found in plant’s cell membrane, roots, and other parts of the plants. Its uses include the following:

  • Fight against pests and illnesses
  • It helps strengthen the structure of the cell wall
  • Calcium helps the fast absorption of other nutrients
  • will help to move the other nutrients in the whole plant
  • Calcium will help in the transformation of nitrogen into a form in making plant’s enzymes for the whole system usage
  • it will help in turning on and off the other nutrients
  • helps a lot in keeping the permeability of the cell
  • it improves the strengths in leaves and stems
  • Helps in the respiration process making the plant to fight the stress caused by too much heat

The ability of the calcium will merely depend on how you maintain the right PH level of your medium. For hydroponics, your PH should range from 5.4-5.8 and for soil it should be for 6.5-8.0. This means that the above ranges should always be maintained to make sure that calcium will work well in your plants or else it will cause calcium deficiency.

Calcium toxicity

Calcium toxicity is difficult to diagnose. You cannot see its toxicity symptoms just through seeing the discoloration of the leaves. You can identify that your plant is experiencing calcium toxicity if you can see signs of manganese, potassium and magnesium deficiency. Calcium deficiency will lock out the latter nutrients.

Signs of deficiency

It is important that you will know the signs of calcium deficiency in your Marijuana plants. The calcium deficiency signs can be identified if the leaves will start to have yellow spots and the tips of the young leaves will turn yellowish. The yellow tips will then spread among all the leaves both young and old and every edge will start to curl and it will then show signs of deformations. The overall sign of calcium deficiency is stunted growth and weak branches.

2)    Magnesium

This second element also plays an important role in the whole growth of the plants. Magnesium can be found in the leaves, it is very vital in chlorophyll molecule and it helps a lot in the enzyme production. Since magnesium is very vital in the chlorophyll molecule, lack of magnesium will surely result to stunt growth. Magnesium will be fully available in the soil if its pH will be maintained between 6.5-8.0 and 5.8-8.0 in hydroponics.

Magnesium toxicity

The sign of magnesium toxicity is difficult to diagnose. The only way to know if there is magnesium toxicity is a calcium lockout.

Magnesium deficiency

The toxicity and deficiency in magnesium are quite different stories. While magnesium toxicity is rare and difficult to diagnose, magnesium deficiency is easy to detect and to be treated. If you will see signs like the tips of the older and Middle-aged leaves will turn to yellow and the space interval will be dark, then it is a clear sign that your Cannabis plants have magnesium deficiency. If it will not be treated right away, the problem will automatically jump off to the new and young leaves and it will then get necrotic spots which will lead to death. Another sign is if the stem and leaves of your Cannabis plants will turn purple. Lastly, when your leaves will start to turn yellowish and the veins will turn into dark and if there will be necrotic spot, you should start to find a solution to solve this problem.

3)    Sulphur

Although sulfur is the last secondary nutrients, it doesn’t mean that it is not important in the growing process of your Cannabis plants. Sulfur will be distributed in the whole part of your plants. Its functions are the following:

  • Sulfur is a major component of protein
  • it helps in the increase of root growth.
  • Helps in the distribution of the chlorophyll
  • has a big role in the production of root nodule legume
  • helps increase the overall growth
  • helps a lot in the transformation of the proteins
  • has an important part of the amino acids
  • Helps in the transpiration of the plants
  • Helps in the metabolism process

All of the stated functions are commonly executed in the flowering stage; however, it doesn’t mean that sulfur has no use in other stages of Marijuana life cycle. Sulfur is a kind of element which moves slowly and it is being distributed in the whole plants. For better absorption of sulfur, your soil should be in a right pH which ranges from 6.0-8.0.

Sulphur toxicity

Its toxicity is rare and among its signs is slow growth and leaf deformation.

Sulphur deficiency

On the other hand, sulfur deficiency is easy to diagnose and identify. Most of the time, lack of sulfur will show signs of yellowing of leaves and curled leaf in the tips. All in all, sulfur deficiency will result in weak growth and purple or reddish stems.

Fixing the toxicity of the secondary nutrients

Since toxicity of these three elements is very rare to happen, you cannot fix its toxicity with just getting one element. The best thing to do is to flush off a pH adjusted level of water in plants if there are signs of toxicity.

Fixing the secondary nutrient deficiency

Basically, the application of Ph leveled water and the application of the deprived elements are the ways to treat the secondary nutrients deficiency.
