I know plants get flushed out faster and more effectively in hydro over soil, I was wondering how long do people here flush their HYDRO plants for? I know for soil it's 10-20 days but I have heard you can go up to the last 4-7 in hydro with good results, considering the nutrients through the bud swelling stage really helps with yield. For the record, my nutrient solution gives instructions to flush with a weak nute mix for 3 days then pure water for the last 4 days, making it a 7 day flush altogether. Does this sound right?
Run ph balanced fresh water 10-14 days before harvest. You will see the nutes start to deplete from the leaves. -C
