Hm, looks like genetic leaf twist is common to Blueberry and this is half Blueberry genes...
Seems weird that the plant I took it from hasn't also done the leaf twist, though. I took the clone before flowering started, and this has only happened on the newer growth. Maybe it needs more light??
It's also only at the top. The bottom leaves are much smaller (the CFL has shitty penetration) and they aren't twisted like the leaves from the top shoot.
