So do mine. We had a heat wave here in the Bay Area and a few of my plants have that curled leaf and crispy burnt look too. I woulnd't worry, they will grow out of it before you know it. Good luck.

Some leaves on my tomatoes have curled and have a burn mark on them. Come to think of it one or two of my squash does also.
My DH says I watered them to late and the water damaged the leafs?
Could this be true?
If not then what?

Leaves can curl if it's too wet, too dry, too hot, too cold, if there's a heavy fruit burden and some varieties have leaves that curl normally, mostly hybrid varieties.

So I ignore curled leaves unless and until other symptoms appear.

How big are the plants right now?

What color, shape and size are the burn marks you refer to and are they on all the tomatoes leaves or just some? And were the plants hardened off before being set out?

If the curling is in-ward and towards the ground it could be too much rainy, cool weather. My plants were doing good until we had 7 inches of rain, temps in the mid 40's made my plants curl up with dark spots that ruined some of the foliage. Oh well just wait for them sunny warm days.

It's not so much the dark spots ruining the foliage that I'd be concerned about, it's the possibility that your plants have acquired a bacterial or fungal foliage disease which if not checked can be very bad for the plants.
