The product label here for Peters Professional 20-20-20 gives the rates based on PPM needed for common injection ratios. If you are referring to a hose-end sprayer, then keep in mind that the Peters Professional is a water-soluble fertilizer that would not work in a hose-end sprayer. If you are using a watering can or tank sprayer, then use 1 tsp of the Peters 20-20-20 in 1 gallon of water will create approximately 238 PPM of N.
