My pole beans are growing in a pot with corn. The upper leaves are nice and green. They get fertilized every other watering with Foxfarm grow big. Their soil is new. The lower leaves are turning yellow and getting modeled. Why is this happening? I haven't seen any eggs underneath them or any bugs on them. Thoughts?

Browning edges can indicate too much water. A plant pushes water through to the edge of its leaves, and if given in excess, this can cause veins at the edges to burst, which leads to browning.

Pole beans lose their lower leaves normally. As they are growing tall, expanding and producing fruit, they slough off the older and unproductive leaves. Part of the reason could be the less light they are getting or just senility. They are no longer needed.
It is just what pole beans do in my experience. I would gladly trade a few leaves for a handful of beans for supper!

Should I remove the old leaves?

I do. They are just draining the plant so I remove them from pole and bush beans.
