Cal-Mag Plus (2-0-0) 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 and magnesium deficiencies. Gardeners can use Cal-Mag Plus as a supplement with standard nutrient formulations or as a foliar application for plants grown in soil and hydroponics systems.
