Specially designed to correct physiological nutrient disorders caused by calcium and magnesium deficiencies. Improves the mass flow of nutrients within the phloem and improves the translocation of carbohydrates. Calcium deficiency retards growth of stems, leaves, roots and causes blossom end drop and die back. A calcium deficiency also reduces thickness of leaves and interferes with proper transpiration. A magnesium deficiency inhibits photosynthesis, the main engine of biochemical energy for plants. Periodic maintenance application of N-CAL-MAG will increase the synthesis of chlorophyll and help with overall health and vigor.
