About Calcium Magnesium
Calcium and magnesium are two of the most common deficiencies in indoor gardens. 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.
