Flush advice needed my fellow growing buddies

With pure organics you dont even really need to flush - you fed the soil and mircobes the whole grow which made nutrients available to the plant to consume when it wants them rather than force feeding the roots with dodgy synthetics that build up salts - I bet your only biobizz liquid that has any salt crystals accumulating on the bottle cap is your pH-? And even when you flush you are gonna keep using that one. The leaves will start fading in a couple of weeks when the plant goes into the end of its life and you will have some glorious buds! When daily water intake drops and leaves start fading stop feeding and just go to pure ph'd water until the end.
