If you want more phosphorus and potassium go with the Liquid KoolBloom. Personally I use FloraBloom and it works like a charm, I even cut the dosage to 1/4 since I grow a lot of autoflowers, but when I grew a few a photoperiods and used the same feeding regiment they did great. Hopefully, I answered your question and remember Happy Growing and Free your mind one puff at a time.
