Help needed to ID browning/spots of leaf edges
Hoping to get help diagnosing this problem with my tomatoes: On both older and newer leaves toward the bottom of the plant, there are black spots and brown around the whole edge of leaves. This seems to have gotten worse in the humid weather we've had. There are some black/brown spots on the stems as well but I don't see any canker area or stem problems like bacterial canker is supposed to have. I do have a couple peppers with similar edge of leaf browning.
Detailed pics are at the link. The plants are otherwise doing great. Any ideas? Is this marginal edge browning related to some other fungal disease?
Would be most grateful for a reply. I'm loathe to tear out otherwise good looking tomatoes by jumping the gun. :-(
