tomato leaves in bsmt. brown spots consuming leaves
Hi turnkey, you don't need to take pic's of the whole plant but try remove a branch that has a few damaged leaves so we can have a look at the problem to try help you, try take the branch into good light for the picture and send as soon as possible, there has been a lot of failures with Tomato, Cucumbers, peppers and potato's have all come under attack this year and from all accounts the main problem is a disease called Blight BUT, no one will be able to give a proper diagnose of your problem without seeing it.
Hope this helps you out for now, good luck.
