This is probably anthracnose or downy mildew. I had the same problem with my cucumber plants this year. You should remove the affected leaves and spray with a fungicide like Bonide Liquid Copper or Mancozeb to prevent the fungal disease from spreading to the healthy leaves. Here is a link to the blog post I wrote a few weeks ago that talks about this problem: http://viettes.wordpress.com/2013/07/11 ... -problems/
. Good luck! It helped my plants and they are producing well now.
