so do u flush ???????Cannabis plants are annuals why waste money on putting more nutrients into the soil in the last 2 weeks? there is plenty of nutes. left in the soil and the plant to finish on it's own I.M.O. & yes i do smoke a lot of weed & i do notice a difference between plants that were just watered (flushed) vs. plants that treated w/ more nutes in the last week or two.
if you use organic nutrients you dont need to flush.
if you use synthetic nutes you should flush imo.
i use hesi nutes,so i do flush.
