Your plants are dealing with heat stress. They are closing the leafs in an attempt to keep moisture in. In other words, your grow area is either too hot, has not enough air circulation/intake/exhaust or your lights are too close.

Reason why I know this is because I came home to find a couple of my little ones doing exactly what yours are but, only four of them are doing this. And they are doing this because the fan leafs of those four were physically touching the CFL bulbs I have them under. I was gone for one day to come home and find that they grew more than I thought they would. But everything happens for a reason and I think this happened to me so that I can help you.... So I raised the lights and they should be fine by tomorrow.... I have plenty of circulation and my cab is steady at 77 degrees so I can rule that out and the fact that only those four are doing this helps confirm....

Hope this helps you....
