Soil and hydroponic gardeners can use Technafloras MagiCal (2-0-0) to supplement calcium (3.25%), magnesium (1.25%) and iron (0.11%) to their regular feeding schedule and promote healthy leaf growth. MagiCal is also great for treating these specific growth-inhibiting nutrient deficiencies and improving fruit density and nutritional content. Unlike similar products, this unique blend is completely water-soluble for immediate plant availability during each stage of development.
