    Hi Sherry, it could be a couple things- rust ( a fungal disease ) can start that way spread by working around them when the leaves are wet, or even not enough water, or conversely, water spots burn on leaves if you water during the hot afternoon. Could possibly be Mexican bean beetle damage. Check for small beetles that look like lady bugs, except they are orange with larger black spots. The larvae will show up later looking like bright yellow fuzzy corn kernels. Fertilize your beans with an organic fertilizer or compost when the leaves are dry along the row gently working it into the soil. I hope this helps!

    my mom would always say that when plants had yellow spots on that them that the sun was burning them due to it being to hot.
