I have about a dozen bush bean plants in several different containers. Some of them have been producing beans since June and others are first flowering now. I've noticed they all have quite a few yellowing leaves. I don't see any obvious insects (like aphids or white flies) on the leaves. Could this be a nutrient deficiency problem or something else? I do keep them all well watered. Does anyone else have these problems with beans?

I appreciate any advice you can give me.

#1 yellow plant problem is generally water, too much.

Too much water is my guess too, although it can also be at the beginning of too much water.

My first thought is not too much water, but an issue with nitrogen. Likely not enough because beans love nitrogen, or too much nitrogen if the leaves are curling.
You may have the proper mix of nutrients in your soil, but the make up of it might be making it difficult for the plant to take in those nutrients. Could also be something eating at the roots causing poor intake.
While everyone else says too much water, you may need to flush the plants well and add some microbes to the soil.

Tap water can also be hazardous if there is too much chlorine in the water as that will mess with the whole 'system'.

When our tomato plant leaves began looking yellow, I researched & found that they needed magnesium.

It was recommended to dilute some Epsom salts (magnesium) in water, to water them with once in awhile.

We did so, and the leaves greened right back up again.

I wonder if that might be what is behind your bean's yellow leaves.

Beans are not the same as tomatoes, but, they are vegetables . . .

Yellowing is generally overwatering and diluting/washing out the primary nutrients in the soil for healthy growing plants. Check your watering and add the fertilizer nutrients as needed per instructions and keep an eye out for insects. Basic stuff.

Thanks again, everyone. I'm watching the watering for now & trying a shot of Miracle Gro. If that doesn't help, I'll try epson salts next for the Mg.
