Leaf Origami

Sooo..I'm curious if anyone knows why my leaves are doing these strange bending/twisting routines. I have two plants in FFOF, 4 weeks old under CFL's. The temp stays between 74-78, humidity is between 42% and 47%, lights are on 24/7. Just curious what causes the twisting/lifting/bending..? Thanks guys!

i donno honestly

when that happens to me i find it's usually to much food...pretty rare, but I imagine some are just like that
I'd call it stress...it's in the dirt...something is off?

I do need to PH the soil and i'm pretty certain that a flush will fix the leaves. I just wanted some input before flushing and re-adjusting feeding schedule. Not so sure the leaves bending like that are a big deal either way. Thanks for the input, Chubby. If you happen to find anything on this issue, PLEASE post. I have never seen anything like this and havent found any other posts with similar issues, and trust me, I put in a lot of time researching it.
