Cal-Mag Xtra is a calcium and magnesium supplement, nutrients that affect the growth of your plants. On the one hand, calcium is an important element for cells; on the other, magnesium is linked to the light absorption process and is essential for chlorophyll.

In addition to these nutrients, the formulation includes chelated iron to act as a catalyst for essential reactions in plant metabolism. For each nutrient in Cal-Mag Xtra to work at full capacity, it includes 20 amino acids in the form of L. These contributions justify the difference with classic Sensi Cal-Max.
