It is particularly useful when growing with soft tap water or reverse-osmosis water, which can contain insufficient levels of these essential secondary nutrients.SUPPORTS GROWTH AND PHOTOSYNTHESISCalcium contributes to strong plant cell walls and helps support natural stress tolerance, while magnesium plays an essential role in chlorophyll production and photosynthesis. Together, these nutrients support plant strength, nutrient transport and healthy development throughout growth and flowering.HELPS PREVENT DEFICIENCIES AND LOCKOUTInsufficient calcium or magnesium may contribute to yellowing leaves, restricted growth and reduced plant vitality. Biobizz Calmag provides a carefully balanced organic source of both nutrients, helping prevent or correct deficiencies while maintaining nutrient balance when phosphorus and potassium boosters are used during flowering.SUITABLE FOR SOIL, COCO AND HYDROPONICSThe lightweight liquid formula can be incorporated into soil, coco and hydroponic feeding programs.
