Any ideas What this is?

Hopefully not late blight. Any ideas what this funk is. It starts at the edges.

It looks like "crud" (non-fatal leaf margin necrosis of speculative
origin), familiar to Kellog's Breakfast fans. I have seen it this
spring on Brad's Black Heart plants, too. The symptoms
resemble what happens to houseplants that are overwatered.

Some tomato genotypes show marginal leaf scorch when grown in artificial media. This is apparently some sort of toxicity associated with the growing mix. The symptoms go away on newly developed leaves after the transplants are put out into regular field soil. If it shows up on all varieties you are growing, it could be salt burn from excess nutrients accumulating on the leaf margins.

It has pretty much just showed up on Dwarf Heart type varieties. Maybe a little on a couple cherry plants.
