Botanicare Cal-Mag Plus 2.5 gal

Cal-Mag Plus CAL-MAG Plus™ is a bio-catalyst for plants and is a custom blend of calcium complex with nitrate, nitrogen and a highly-soluble form of chelated magnesium. This combination helps stop blossom end rot in tomatoes and prevents calcium, magnesium and iron deficiencies found in most soil fertilizers and some hydroponic nutrient liquid concentrated formulas. Use as a supplement with standard nutrient formulations or as a foliar application.
