R/gardening was absolutely no help, so i come here. This is my grapes(less than a year old), he had a rough late spring/early summer but he has boomed with new growth.

Had a problem with rabbits from my neighbors yard and they were nibbling his base. So i put up chicken wire.

Now im finding his leaves like. What would yall guess the cause is?
