I have been having trouble with a few plants. The leaves have yellowed on my oldest chinese varieties in pots. Other than the color they are still growing and producing pods. I have been giving all my plants a spray of Epsom Salts every 2 weeks. They just received a spray on Tuesday. They also have pelleted fertilizer scraped into the top of the soil. I had been using fox farm's products but since it basically rained from the end of May through June I added the pelleted stuff at some point in June. It is supposed to last several months. With Nitrogen and Magnesium covered I am wondering if I have some type of other deficiency going on. I have 2 chineses of the same age etc. planted in my raised bed and they look great.
Here are some photos of the yellowing...
