Calcium & Magnesium
Coco tends to bind itself to calcium and magnesium a little too easily. If these secondary macronutrients are bound to the medium, they won’t,of course, be used where they’re needed most – in the growth and development of your plants. Over time, this will lead to deficiencies,leaving your plants more vulnerable to pests and diseases and drastically reducing potential yields. Luckily, Advanced Nutrients’team of leading scientists have included optimised levels of calcium and magnesium to ensure that this is never an issue.
or should i buy it just incase.
