Jack's 15-16-17  is a nice variation of Geranium Special 15-15-15 with slightly elevated micronutrients.  With a ratio similar to 20-20-20 but with over 60%  nitrate nitrogen, boosted micronutrient levels, and much less acidic reaction in the root media. The balanced N-P-K ratio is excellent for producing fast-growing plants or for maintaining plants in a sales environment.

Mixing Instructions

Chart  displays the amount of dry fertilizer (oz.) to add to each gallon of  water to make a concentrated solution. Please check your injector  setting before use.
Limit of Solubility = 4.5 lbs per gallon

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.
