Rusty, to clarify my answers to feeding... and thanks very much for the reply... The nutes are all included in the Flora series... per GH factory rep who has been helping me with feeding. I mix nutes in water, then ph to 6.4 I had not been doing that up to a few weeks before I noticed problems... had been running 7.8 well water. Yikes.

I will definitely mix up my nutes at 1/2 strength now and apply all at once rather than a "nuted water then clear water" method I was using.

The plants look great now. New growth is looking normal since the flush. Waiting for plants to dry out before adding new nutes.

I am concerned about the comments about #4 getting acidic and you having to change soil after they are in flower? Can you expand on this?
Thanks
