Hi and thanks for contacting Ask an Expert.
Your bean leaves are sunburned. They need to be shaded. You can buy small amounts of shade cloth at nurseries and put it on pvc pipe cut and stuck in the ground or if you have a lot of bean plants, buy 1/2 inch pvc pipe 10 ft lengths and push each end into the ground on either side of the beans (approx. 4 feet apart), put the shade cloth over it. It does not have to go to the ground on either side. The shade cloth has holes in it; you can tie it to the poles or buy clips and clip it on.
The weather is supposed to be 90 degrees for the next four days so they will burn if not shaded in the very hot weather.
Plants also do not grow or produce in the very hot weather. They wait until it gets cooler to start growing again. Water either early morning or late evening on the ground, do not splash the leaves. Wet leaves during the day will burn as well. Keep your plants well-watered during this upcoming hot spell.
