@Canabetter024, you don't need to flush. It's counterproductive and does not improve smell. Proper curing is for that and plants need nutrients in end of flowering more than ever.
@phistowarrior024, Depends on what feed additives (organic or synthetic) recommend to add at least one meal and start to flush 10 days at least before harvest, and 2-3 days before harvest forced flush (1/3 of the volume of the pot ),after that i give 2-3 days darknes and cut them !
I hope that I have helped ๐๐๐
