with hydro, you need to flush for 2 days with water only. get some final flush and add 10ml per gallon,let the flush work for 5 days. turn lights, pump, air stone, etc. off for 24 hours. cut plants, trim leaves and hang.
mobay Reviewed by mobay on . FLUSHING OUT NUTRIENTS!!! HELP! I need your help please. I am currently "flushing" the plant, as it is ready to harvest. I have been using PHd water with ZERO nutrients in it for a week and 3 days now. How do I know when it is completely flushed of that cr@p? A friend of mine who has grown in the past told me to wait until there is no more green in the leaves, they all die and turn yellow. Is that true, or am I killing the potency of the bud by doing that? How long should I flush? Am I doing it right? When Rating: 5
