Dutch Pro Calmag

Calcium and magnesium are secondary macronutrients and play a huge role in plant development and growth. Without the correct levels, plants will simply never reach their full potential; this is a particular problem in soft water areas, where the tapwater has a starting EC lower than the usual level (around 0.4 to 0.7). Adding calmag is an easy and quick way to correct the situation, and it will keep your plants flourishing. 

As plants progress through the bloom phase, the demand for magnesium and calcium increases; therefore, most growers can benefit from using calmag at this time, especially if they’re adding big doses of PK boosters (phosphorus and potassium).

Calmag is also beneficial for growers that use coco, as coco coir breaks down and releases extra potassium, which raises the plants’ requirements for calcium. Ample levels of calcium (Ca) help maintain the integrity of cell walls, and Magnesium (Mg) forms an integral part of the chlorophyll molecule.
