Hi Leslie, thanks for the question.
The leaf curling is most likely a stress response. This is known as physiological leaf roll. Hot temperatures, heavy pruning, root injury, water issues, et al can are potential causes. The spots appear to be Septoria leaf spot. Fungicides work best as a preventative but can slow the progression of the disease. Check out the following links for more detail and control/ management:
