Cal-Mag Pro Formula

Blue Planet Nutrients Cal-Mag Pro Formula is a highly concentrated water-soluble powder supplement that corrects and prevents deficiencies of calcium, magnesium, iron, nitrogen, sulfur, manganese, zinc, boron, molybdenum, and copper — covering nearly the full spectrum of commonly deficient plant nutrients in a single product.

This multi-nutrient approach makes Cal-Mag Pro more comprehensive than standard CalMag products, which typically provide only calcium and magnesium. The included iron supports chlorophyll production; sulfur enhances terpene formation; manganese, zinc, boron, molybdenum, and copper all participate in critical enzyme and metabolic functions that become limiting when soils are depleted or when growing in inert media.

Being a powder, Cal-Mag Pro is highly concentrated and cost-effective at scale. Dissolve at the recommended rate and add to nutrient solution throughout the grow cycle. Compatible with all growing media and nutrient programs. Made by Blue Planet Nutrients, an Oregon-based company.
