Tomato plant issue

I have spots on my plants too ...but the tomatoes are ok.
Are yours still cropping?

Sounds a bit similar to the problem I have had this year with my outdoor tomatoes (Gardeners Delight). In my case the stems also have black blotches and many of the fruit have rotted. I have contained it to some extent by taking off affected leaves and getting rid of all the tomatoes that have been affected. I am assuming it is tomato blight and is caused by the constant waterlogging of the ground.
