Every marijuana grower can find themselves in a situation when their marijuana plants have a strong need for nutrients for normal growth. Keep reading, and you will find out how to solve the problem of nutrient deficiency in marijuana plants and what nutrients for cannabis are the best to use.
1. Alfalfa and cottonseed meal
In order to correct the nitrogen deficiency in marijuana, many marijuana growers add alfalfa and cottonseed granulated products to the soil. This refills the soil with protein that counteracts the nitrogen deficiency. The pressed alfalfa hay acts as a slow-release nitrogen fertilizer when it contacts the soil. More than that, alfalfa contains trianconatol, a fatty acid that stimulates the plant’s growth. Cottonseed meal also has a high level of nitrogen in its content. However, because of the pesticide use in cotton fields, you need to be very cautious and use only pesticide-free products on your cannabis plants.
Cal-Mag is not recommended for use when the cannabis plants are at the flowering stage. Otherwise, the flowers will absorb too much nitrogen. The best time for using this treatment is the vegetative stage. To make the roots of cannabis plants absorb calcium and magnesium, you need to create the proper pH conditions (6.5). Otherwise, calcium will result in the formation of dead spots in the leaves.
3. Calcium Nitrate
This is one more way of correcting the calcium deficiency in the plants. Calcium nitrate contains 15% of nitrogen and can increase the pH level of the soil if it is needed. Again, do not use this option at the flowering stage.
4. Chelated minerals
Chelated minerals are important for marijuana’s ability to transport oxygen and various nutrients. The most widespread usage is liquid fertilizers dealing with copper, iron, and zinc deficiency. The majority of hydroponic systems contains a mix of chelated minerals.
5. Granite dust
Granite dust is a perfect source of potassium. More than that, it can stabilize the level of alkaline in the soil you use. To make this option more effective, the growers recommend to mix granite dust with a 50% mixture of compost.
