Hey Meanyaf, From your pics, it looks like a coupe possibilities. 1) If your temps get over 80 degrees, it could be the leaves are heat stressing. That can cause curling up of leaves. Another possibility, since the plants generally look great, is that they're growing so fast that the leaves are just trying to catch up. I had a purple kush photo that did that- no other issues, just clamped up from 2 inches of growth a day for a few days.
Hope that helps. Good luck!

Also, you should go to the introductions forum, and introduce yourself. Folks here are great.
