Cal-Mag is a partial spectrum fertilizer that contains just calcium, magnesium and nitrogen. Its main purpose is to fix water with very low mineral content. Its also useful as a first aid product for correcting calcium, magnesium and nitrogen nutrient deficiencies, both in solution and as a foliar spray.
Cal-Mag is typically not used with hard water because hard water usually has calcium and magnesium in it already and doesn’t need any more.
Cal-Mag is most commonly only used to treat soft water, low mineral content water that is deficient in calcium and magnesium.
Cal-Mag transforms low mineral content soft water into average mineral content water that other fertilizers are compatible with. As a preparation step, Cal-Mag gets added to soft water before all other fertilizers.
If the dissolved solids in your water are less than 0.3 EC (150 TDS) add Cal-Mag and raise the mineral content of your soft water to 0.3 EC (150 TDS).
To treat calcium, magnesium, or nitrogen deficiencies apply Cal-Mag in solution or in a foliar spray.
Cal-Mag is not a complete fertilizer solution for your plants. Use in combination with other fertilizers.
