Cucumber problems

[aclum]

Trouble in paradise here . The leaves on my kratky cucumbers seem to have picked up some disease. (I've inspected the plants and haven't seen any critters). From looking at pictures on the web, I'm guessing the damage is caused by some sort of fungal disease . It's been very warm and dry here and the plants don't get watered in a conventional sense, but they're only a few feet from our lawn and might have gotten some overspray from the sprinklers (especially with the wind gusts we've had recently).

I'm attaching some photos to see if anyone can give me a diagnosis and treatment recommendation. I kept the photos larger than normal so it would, hopefully, be easier to figure out what's going on.

Thanks for any input!!
