The story of nutrition for cannabis and hemp goes beyond the macronutrients of nitrogen, phosphorus, and potassium. Calcium and magnesium, two secondary plant nutrients, also play important roles in plant development and productivity. Cannabis is a particularly heavy consumer of both.
What exactly are these two nutrients doing inside your
plants? Calcium provides structural support to plants as they develop,
strengthening cell walls as new tissue grows. Plants lacking in calcium can
display symptoms such as tip burn on new growth or pronounced leaf curl. For
some crops, calcium deficiency even manifests as damage to developing fruits.
While calcium builds the foundations for your plants’ structures, magnesium
keeps the energy flowing. Magnesium is the atom at the center of all
chlorophyll molecules, enabling plants to photosynthesize. When magnesium is
lacking, chlorophyll in older growth breaks down and magnesium is remobilized
to new growth, leading to lower leaf yellowing.
It can be difficult to meet the full needs of some crops
through the use of complete fertilizers alone. Growers find that fertilizers
high in calcium can often affect the pH of their substrate, typically leading
to higher pH conditions. Some growers avoid with these conditions by rotating
fertilizers, while others carefully build balanced fertilizer programs. Talk to
your Griffin sales rep to find out how GGSPro can help.
An additional option is selecting specialized calcium
supplements without adding a complete fertilizer package. Plant-Prod MJ Spike
(CaMg) is part of the cannabis-specific line of nutrients from Master Plant
Prod. This product has been specifically formulated to deal with the
high-calcium demands of cannabis production and can be used any time throughout
the production cycle. Both calcium and magnesium are provided in a beneficial
ratio of 2:1 – 5.4% Calcium, 2.7% magnesium. Chelation with EDTA keeps the nutrient
ions fully soluble while in stock tanks and during application. This highly
specialized product is free from any other nutrients, ensuring that other
nutritional ratios are not thrown out of balance. Ask your Griffin sales rep
about MJ Spike or any of the other MJ Line fertilizers from Master Plant Prod!
