Tomato Plants have dark green, curling leaves!

It's been years since I planted tomatoes - now I remember why I stopped.

They've been fertilized. At first I thought I was over-watering. I found a couple caterpillars on them, but I've never seen leaves getting so thick and curling downward.

We're having a heat wave - could that have anything to do with it?

For tomatoes, a heat wave is several days in a row with nighttime temps over 70 degrees and daytime temps over 95 degrees. I would give them water by soaker hose or drip--at the bottom of the plant--only about once a week, or whenever the root area begins to look dry. I would also throw some cover over them during the sunny part of the day to help shade the leaves. During heat wave conditions, there's not too much you can do about another condition where the blossoms drop off and you lose that round of fruit until conditions get cooler.
