Jack’s Professional LX All Purpose Fertilizer 21-5-20
This is the ideal fertilizer for moderate to high alkalinity water. This complete formula keeps magnesium and phosphorus soluble in concentration giving the grower ultimate flexibility when adjusting their nutrient program. It can be tank mixed with 15-5-15, other Jack’s LX formulas as well as Calcium nitrate and or magnesium nitrate. For use on all bedding and potted plants, can be used for plugs at low rates.
Great for growers who want a general-purpose formula that is potentially acidic. Great as a lower P alternative to 20-10-20. Very flexible formula that can be tanked mixed with other LX blends without reducing micro nutrient concentration.
Mixing Instructions:

E.C. value is the best method to determine fertilizer strength. Fertilizer appearance may vary in color due to variations in raw material size and tracer dye distribution upon the particles in the bag. In solution, the 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.
