Cal-Magic is a premium organic Cal-Mag supplement made with unique, nutrient-rich ingredients like kelp meal, rabbit manure, seabird guano, crab shell, oyster meal, and fishbone meal. These natural sources deliver highly bioavailable calcium and magnesium—crucial for strong cell walls, healthy fruit development, and preventing deficiencies. Unlike synthetic Cal-Mag products, Cal-Magic does more than feed your plants. Its 3-4-4 NPK formula supports vigorous growth, abundant flowering, and resilient root systems while enhancing soil health by boosting microbial life, water retention, and structure. Suitable for all grow stages and mediums—including soil, containers, coco, and hydroponics—Cal-Magic is easy to apply and can even be brewed into a fast-acting tea.
