SUPERthrive Mag-Pro Supplement 2-15-4, 5 Gallon – 5 Gallon

SUPERthrive® Mag-Pro® Nutritional Supplement 2-15-4 is a high-phosphorus supplement containing magnesium and sulfur designed to support flowering and fruiting stages when used alongside complete nutrient programs. This formulation provides additional nutrients required during critical growth phases where enhanced bloom development is needed. It is intended to be used in conjunction with base nutrient solutions rather than as a standalone product, helping provide targeted nutritional support during reproductive stages. Suitable for use in soil, hydroponic, and soilless systems, it is particularly useful when using purified water sources that may lack essential minerals. The nutrients are readily available for plant uptake, supporting consistent feeding programs and helping maintain balanced nutrient availability throughout flowering cycles.
