I have heard that said dozens of times over the years.I've been growing about 13 years now and I've come to a conclusion and that is more is more.When my plant has a few nodes I use a tsp of PBP grow.Around 400PPM.As it gets larger 2 teas.and then 1 tbls(15 ml when they are a couple feet tall.All this time I have used it every watering.Dont try this with fox farm grow big you will burn thr fuck out of them.Anyway,the first couple weeks of 12/12 I'm still feeding 15 ml of PBP grow.Then I switch to fox farm tiger bloom the best stuff on earth.I feed 2 teaspoons every watering except for the last 10-14 days I give pure water.Dont be confused I know you've heard less is more probably a hundred times.Just try my way once I'm really trying to help you.Hell on PBP grow it says use every watering.Remember R/O water needs cal-mag
