Sul (2.2%)-Cal (5.5%)-Mag (1.6%) 

Did you know Sulfur, Calcium, and Magnesium are also Macronutrients? Sulfur  is a structural component of amino acids and vitamins, and is essential in the manufacturing of  chloroplasts . Calcium  regulates transport of other nutrients and is particularly important in root development, with roles in cell division, cell elongation, and the detoxification of hydrogen ions. The outstanding role of  magnesium  in plant nutrition is as a constituent of the  chlorophyll  molecule. As a carrier, it is also involved in numerous enzyme reactions.  Application: Mix 1/2 – 1 tsp per gallon of water. Apply every 1-2 weeks, depending on feeding schedule and plant cycle.
