With a good organic grow, flushing isn't needed. I don't expose my Babies to something that needs to be taken away at a later date. While in final flowering, a LOT of moisture is needed for the sticky buds. I stop the fish emulsion, watering more than normal- a semi flushing, but continue with the molasses & seaweed. I stop that when tricks are clear, then just lots of water. That also allows good regen, and the taste is the rave.
