curling / wrinkling persist help plz?

Whats up guys this is my second run and I love doing this stuff. I'm having a problem with the upper fan leaves wrinkling and canoeing , also there is a paper re feel and touch to the leaves . I am running a few different strains in 3 gallon pots with ffof and a perlite mix, with half strength feedings of general organics go line. Conditions are good ventalation, lighting ect. They all have been thriving up until this point. Please help?

They look good to me, it could be just that the leaves are still growing out. Most of the newer growth on my plants have a wrinkled look to them until they grow out. Good luck!

Normal. Nothing to worry about.

Sounds like me lol. yeah, i use the same GO line and have good conditions. I have noticed that on new growth as well but it will go away when they grow out. Seems to be the norm...

I'm a newbie and I suffered severe curling and wrinkling. I betcha anything your PH is off. ask the experts around here but my advice is get a tester and test your ph. get it right and you're plant will stop that. most of mine even uncurled which is never a guarantee.
