CALiMAGic is a low nitrogen calcium magnesium supplement, specially formulated to prevent secondary nutrient deficiencies in fast-growing plants. Many calcium-intensive plants, like lettuce and tomatoes, need that extra Ca+ boost to optimize growth. This prevents diseases related to calcium deficiency like blossom-end rot. CALiMAGic also prevents leaf tip burn: drying and curling leaves due to a shortage of calcium in leaf tissue.
