I had the same clawing as I did with the 1 gallon run. Still not sure what is causing that. It happened at around the same week of flower (2-3) so maybe this geno is just sensitive at that stage. Either way, it didn't impact things too badly, I hope. This is from 11/27.

Who bred the key lime chem? are you still using the bat guano? if you are that could be the reason for that claw, but these things are so complicated. Sometimes it takes me years to find out what I did wrong.
Wow! You got totally different phenos than I. I had 2 phenos from 2 plants, one was a bleeding pheno that foxtailed like crazy and looked like your A12. The other looked like A4. Ran into some clawing problems... JD Short said the "clawing" could either be nitrogen/PH related or a trait from the F4 Blueberry male used in the cross.
