These are white half runner beans + a few Kentucky wonder, direct sow, back around Mother’s Day. 

Hi Kristina, thanks for the question.

Looking at the pictures, it looks like ozone damage. It appears that Oakland County had some elevated ozone levels on July 8 ( AirNow Interactive Map (epa.gov)).  Not much you can do at this point.  Early stages can look like spider mite damage so you may want to check that out with a "paper test" (see link below).  For spider mites a hard spray of water (especially to the underside of the leaves) or spraying insecticidal soap can keep the population down. Check out the following links:

I hope this is helpful.
