Sure looks like herbicide damage as in Roundup or other product with the active ingredient glyphosate. Applied a week or more ago.

Tomatoes are very sensitive to various weed killers. Just a whiff on the breeze sets them back.

Only time will tell if they grow out of the damage.

Thanks for the reply.Last weekend I did use some roundup around them. I wonder if got too close to the plants. I won't do that again.
Thanks
