Yellow and brown spots on tomatoes (pics):

Any idea whats happening to my tomatoes? Also theres a few leaves on my runner bean going yellow any ideas? Many thanks in advanced!

the yellowing is just a lack of feed , any how the bottom braches can be removed now and the purple on the leaves is nothing to worry about aswell. just remove them if you want

I agree with Rudd, and a little bit of air circulation around the bottom of the plant will not hurt. Most older leaves do go a little purple. The rest of the plant looks healthy enough.
