Going on vaca soon and need to get this under control before I leave and dont have time to search properly.
thanks for some help.

The leaves look nice and green in that pic... they're just kind of saggy, and rolling lengthwise?

I suspect what's happened is that the heat hit them when they didn't have quite enough root system to handle the load -- leaves evaporate water, and in hot dry weather they evaporate a lot. If it was a cool spring, the tomatoes will have grown slowly, and their root systems won't have gotten very large in the cool soil. Then the heat hits, and *blam* they're evaporating more water than their roots can take up. I always see some of this early on, as we tend to go straight from 50 degrees to 85 in a week or two, and then it soars to 95 or higher as the first heat wave hits. It takes the plants a bit of time to catch up.

Water well and cross your fingers for them; you may end up with a few crispy leaves at the end, but they'll rally after the heat wave ends. You may still see a little of the rolling if the sun gets especially bright and hot, because that's their reaction to getting more light than they can cope with.

If you have time to post a picture of the spots, we can take a look at those too.
