Pix is *very* small & challenging to see details. Even so, I suspect weed killer damage used somewhere nearby.

I'd agree (on both the comment on the picture and the likely diagnosis). If it's affecting 2/3 of your tomato plants and a couple of peppers, yet the cucumbers are okay, that rather rules out cucumber mosaic virus; that would be the most likely virus to make curly leathery leaves which are also quite green. If it were widespread enough in your yard to affect that many plants, though, it should have spread to the cucumbers.

On the other hand, Solanums (tomatoes, pepper, eggplant, potato) are far more susceptible to the broadleaf weed killer 2,4-D than cucurbits, brassicas, or Betas. They'd be the first to show symptoms. Look to your yard and your neighbor's yard -- Weed & Feed can drift when sprayed or evaporate in high temperatures.

They may grow out of it if it's not severe, but if they don't start growing well within two weeks or so, I'd say you're out of luck. You might root a few shoots off of the tomato plants that seem to be doing all right, just in case.

i have these exact symptoms. Did you ever figure out what it was, and did the tomatoes recover?

As was said, it's herbicide damage, most likely 2,4-D, possibly dicamba.

Whether or not it recovers depends upon how big a dose the plant received. Only time will tell.

Herbicide damage? I don't hardly think so in my case. I have a pepper plant and tomato plant in a protected place, no herbicides in our yard. It's in the middle surrounded by tall perennials that would block any drift from afar. I am thinking it must be a virus thriving by environmental conditions this year. Been gardening a long time and never seen this on my plants. We had a really freaky winter and spring this year.
