Tomatoes get all sorts of manky bits on their leaves over the season. It may be a sign of over fertilization, but more likely just condensation and may be a draught that's caused it. I snap off all the lower leaves on my toms when they're established to stop nasties crawling on board and improve air circulation
With blight you'll notice black bruises on the leaf stems and plant stems

Knowledge is knowing that a tomato is a fruit. Wisdom is not putting it in a fruit salad.
looks a lot like cold damage, they go blue then turn black if the damage is bad enough. at this time of year its always a possibility. they should be fine
