Hey thanks man. Unfortunately, one died today. It was one I kind of accidentally sprayed some kind of screen printing ink removal chemical on, so it wasn't looking so hot as far as some of the leaves (long story). Luckily I only got it on a small leaf on one of the others, which I cut off and it seems to be doing fine. Its been 5 days now and there are no roots poking through the rockwool yet on any of them, but I am still holding out on the other 4. I took the dead one out and looked at it and the bottom was white and bulgy looking, almost like cauliflower.
