Important Notes:
E.C.  value is the best method to determine fertilizer strength. Fertilizer appearance may vary in color due to variation in raw material size and tracer dye distribution upon the particles in the bag. In solution,  color will remain consistent.
​For best results, use warm water to dissolve product. Jack's fertilizers are made with 100% soluble raw materials that will form a true solution.  Some raw materials are slower to dissolve than others. Keep stock tank covered to reduce light and debris inputs.
