5 weeks, Barneys LSD...All but the very tops seem ready. Here is a photo and I hope I can receive some help. Should I start flushing now and harvest in two weeks or?
8 weeks is a good number, could be 8 1/2, 9, 10, etc. it all depends... Why are you so set on flushing? Do you have nute lock out/ salt build up? If not feed your plants the nutrients it needs until harvest...
