Yellow leaves on bush bean
My son planted two bush beans from seed. We transplanted them to a larger pot and they have given a lot of beans, but now one of the plants' leaves are turning yellow, while the other is doing great. Interestingly, it is the one that bore more fruit that is in poor health. Some of its baby beans are turning yellow too. I noticed it started taking in less water, so I watered it less. Then when it seemed to me that it was taking the water, I thought that could be a good sign and watered it again (yesterday), but today it appears ever more yellowish...
