It wasn't mainly to flush, I'm not a flusher, I never do, (my bathroom stinks..LOL j.k.)
it was to set the medium packed with BigBud formula, and light base nutrients for full compliment of minerals. and they would probably jump in happy bud growth.
Use my suggestion as a guide then, and tweak what works for you. This is all I can do, I've tried to help youo several times, and you seem to just do whatever you want anyway, so why ask for help. We don't know why 1 out of the bunch is different, we dont know why one plant is giving issues and not others.. but if you will only take advice from your own inner voice, this whole thread is useless waste of everyone's time.
cu.
you know what you're doing, you'll figure it out.
