Hi Debbie, thanks for the question.

This is most likely physiological leaf roll caused by environmental stress. Excessive pruning, high heat, low moisture, too much water, damaged roots, too much nitrogen can cause the problem.  It really doesn't hurt the yield, but the rolling usually doesn't go away.  Insects, viruses, and pesticide drift can be other sources for leaf curling.

I hope this helps.
