Beginner Gardening: Snow peas are curling and look sick, 1 by SandyNashville1

First time I've tried snow peas - the golden variety I have has been great up until about a week ago...tasty and beautiful. Now they have started to look deformed, and are getting a little brown. Production is slowing down as it's getting pretty hot here in Nashville, but my snap peas look fine. Could this be caused by too much rain - maybe the snow pea is just more susceptible than the snap?
Thanks for your help!
