Instructions to make up a tank of fertilizer at full strength for crops (no injector):

STEP 1: Dissolve 130 ounces (or 8 pounds 2 ounces) of this material in 1000 gallons to obtain the following concentrations: 

  
  Total ppm
 Nitrogen N 0
 Phosphorus P 64
 Potassium K 243
 Magnesium Mg 54
 Sulfur S 138
 Iron Fe 1.5
 Manganese Mn 0.29
 Zinc Zn 0.09
 Copper Cu 0.09
 Boron B 0.25
 Molybdenum Mo 0.06
                      
STEP 2: Test your water to determine if additional magnesium is required. An average of 50 to 75 ppm magnesium in the final solution is desirable for most crops. If additional magnesium is required, dissolve epsom salts into tank (1 oz of epsom salts dissolved in 100 gal supplies 7.5 ppm Mg). 

STEP 3: After the Peters Professional 0-15-30 Hydroponic Finisher and any epsom salts are fully dissolved, proceed to supplement your crop with required concentrations of N and Ca. (Example: In 1000 gal, dissolve 80 oz of Peters 14-0-8 Hydroponic Boost to add 189 ppm N, 183 ppm Ca, and 12 ppm Mg.)
