CleanGrow’s Cal-Mag product was designed to supplement either of our 2-part formulas. Some plants may require heavier doses of Calcium, Magnesium, Iron and Nitrogen at any given point during their rapid development, and this product will correct these common deficiencies. For “Cal-Mag hungry” plants, systems running RO water, and plants grown in coco, this product will be particularly useful. Although the Fertmax series already contains moderate levels of calcium and magnesium, the Cal-Mag supplement might be helpful for growers with any of the above conditions, as the demand may be higher.
