ECIL the Heartland | Sun scald on first two, definately. Always on bottoms of leaf, right? Does not appear on top side of leaves, as I understand it. bottom pictures not too clear but I would think Bac. Leaf blight (or pustule) as well. Fungicide DOES NOT help BLB. Get a leaf sample to confirm.
Edit- check bottom of leaves of the bottom two pics for a fuzzy white/gray growth. Could be powdery mildew. I don't think fungicide does much for this dease either.
