Don't look so good they are turning yellow and the leaves are dying
I wouldn't worry about it unless you see yellow leaves spreading. It's not unusual to have a leaf or two "peter out" like that. The rest of the plant looks good.
cb-gardener, I would plow or hoe around the plant rows and keep watered. Plants look OK except soil needs loosening up.
Ok i did all that but the leaves are turning on other plants. Should i pick those leaves off?
If it's the bottom leaves, then yes, pick them off. It's normal. But your plants look very close to each other. Pole beans should be 6 inches apart and bush beans even further. Crowded plants are not happy. Maybe thin them out, pulling the weakest ones.
I thinned them out so we shall see if that helps. Do you think that's enough. I also hoed around the plants to break up the soil. They had some blooms pop out.
Yellowed leaves are semi dead and have no benefits what so ever. In fact, the might be host for bad bacteria.
Anyway, your plants look healthy to me.
BTW: How are they arranged? in rows or random? If in rows , the they should have furrows to hold the water. If random, should have a bowl like hill to hold the water. Unless you have different watering method(Sprinkle, drip hose..)
From the appearance of the soil, I get the impression that the soil must be sandy. In that case you'll have to water and fertilize them more often than normal.
