Bloom Calmag is a professional-grade calcium and magnesium supplement formulated to support plant development, nutrient transportation, and photosynthesis. It also contains chelated iron and zinc to promote healthy growth. Calcium strengthens cell walls and supports nutrient movement, while magnesium contributes to chlorophyll production and efficient photosynthesis. It is particularly useful for growers using soft water, which naturally contains lower levels of calcium and magnesium.
