The kids seem to be doing a bit better... I didn't finish up adjusting the ph, but I did put them in a new nutrient solution. If they don't continue to improve I'll look into lowering the ph a bit.

Growth is still occurring.

I haven't been spraying them at all. They have fairly good roots dangling into the nutes and I'm sure they're getting "enough" nutes through the them.
I had never noted that sort of droop before (previously I had been a dirt farmer) and the wilt looked a lot like they were thirsty which really can't be the case.
I'll post a couple of pix later.
Peace everyone.
