Why are my green beans yellow?

Can anybody help me idenify my problem with my blue lake green beans.View attachment 1035011

Do you have alkaline soil? I have to use a soil acidifier just to approach neutral here in the land of limestone. High alkalinity interferes with uptake of iron and will yield yellow leaves like that.

If the soil is properly balanced, it's a disease. But, it doesn't look like mosaic (which blue lake is resistant to, anyway) or blight to me, more like a nutrient problem.

You could try giving them a shot of Miracle Gro and Epsom Salt.
