Does anybody know why this is happening
 

I noticed that some of my plants, the peper plants(2), tomato(1)
clemetis vine ( 1)
the leaves seem to be stuck on one side while the other keeps growing, forming a c shape, that's the best i can explain it, see
for your self,

if you know what is causing this please let me know, it is worring me, i don't want it to spread, and if it is only cosmetic how do i treat it?

LET ME KNOW IF YOU NEED MORE PICTURES

I seen some pics in a book one time with leaves growing in a circular pattern and it was caused by the light schedule being interupted. I dont know if that would have the same effect on your plant though

Too high of EC could cause this. Too much nitrogen causes distorted growth. Insect damage can cause this problem, too. Did you ever get this one figured out?

no i never did, i followed all instructions on feedings, and the strange thing is it is on the plants in my hydro system and the plants outside in pots i had planted, never being close to each other, it seems to have stopped , but the affects are still seen,
