Let me try this again.This focus on this pic is a little off but can anyone tell from this pic what this blemish is on our tomatoes? Thanks Gilbert and Victoria

It could be early blight. Mainly on the bottom leaves? Be sure you don't water on the leaves directly. Not much you can do for early blight. I trim some of the effected leaves/limbs off. Any yellowing?

Yes there is some yellowing....Thank you. We will look into what to do.
