Danielle, the necrotic - white/fawn - tissue in the first photo doesn't necessarily mean "blight".
"Blight" has become a generic term for all fungal diseases. In reality, there are two "Blight" diseases - Early and Late. There are other fungal diseases that can look somewhat like them. Early Blight is the most common fungal disease in the domestic garden, with Septoria Leaf Spot probably next on the list.
This is what Early Blight looks like in its early and later stages:
Notice the "bullseye" appearance of the spot in the first image. I think I can see one or two of them in your first photo. The extent of the necrotic tissue, though, isn't necessarily consistent with a fungal problem. You can get that result from things like fertiliser burn, particularly too much nitrogen. Are you fertilising the plant? And what with?
Can you take another, much closer photo of the smudge/stains on the leaves in your second photo?
