SHAMAN’S Coco Magic Core Formula is truly the core of Coco Magic. Containing calcium and a good balance of nitrogen; the Core Formula is designed to equally unite the Foundation Formula in creating a complete balance of macro-nutrients until bloom is needed. The Core Formula then allows the user complete control over the macro-nutrient balance by either lowering the Core Formula in equal amounts alongside the Foundation Formula or by lowering the Core Formula separately from the Foundation Formula.
