This problem is especially apparent in coco coir, where the coconut husk itself will leech calcium and magnesium out of your feeds. Cal-Mag is a basic supplement, always with calcium and magnesium, but often with other nutrients like nitrogen, zinc, iron, and manganese to provide a fuller spectrum of supplementing and correct for other deficiencies that may be showing as calcium ro magnesium. HTG Supply carries Cal-Mag from all the top brands, including Roots Organics, Advanced Nutrients, and Botanicare.
