so glad i stopped in to check your grow out.

I am also on my 2nd grow and I also have headbands. One of mine is curling just like yours! It seems that my conditions are also not heat or light related as its cold, and Im using a 105w cfl.

You might see if less water helps. The bible says that issue could be the plants attempting to transpire all the time.

Mine have been dry, and seemingly well cared for and I also have curl!? Might be a genetic thing....

good luck to us both!
