There always seems to be math. I bought fertilizer for a professional grow operation and a home garden hose end sprayer. It's not easy wanting the best from both worlds.
Thanks Tim for the research and analysis, I sure do appreciate your effort.
I can recover from using too little via another application. I wouldn't want to know the outcome of using too much though. I'll go with your recommendation and make a gallon of concentrate with 5.4 oz fertilizer.
