Monkey Mag Cal is an important additive if you are growing using coco as the substrate, although you may find it necessary in other medias too. It provides a readily available source of calcium and magnesium, preventing deficiencies before they become apparent. These two vital elements are used up quicker in coco grows than soils, as soil naturally contains some already. A lack of magnesium and calcium will lead to all manner of issues and your end yield will be affected while the plant suffers the consequences.
Adding Mag Cal is a great way to maintain a healthy plant that can grow without restriction. Looking at the schedules below, you’ll notice that Mag Cal isn’t on there as it isn’t essential to the grow, except perhaps in coco. Therefore, just follow the manufacturers instructions on the bottle!
