Curling leaves I think are seen by almost everyone at one time or another and they can be caused by too hot, too cold, too wet, too dry, too windy, etc., and if the leaves curl over into a tube structure then consider aphids.

So varieties, especially some hybrids, naturally have curled leaves and leaves can also curl if the fruit burden on plants is high. And they can also curl early in the season for any variety until the plant becomes mature.

I agree with Carolyn. Young plants often curl until they get established.

Might want to rethink your watering strategy though. Tomatoes have the ability to root VERY deep if you give them the chance. Consider mulching as well. I too have sandy soil amended with compost. I also mulch. I live at a high altitude and it gets very hot during the day. Once my tomatoes are established and mulched, I rarely have to water them. Watering them daily will tend towards shallower roots. Let them search a bit for water, and if you mulch with organic matter, you will water less by default, and also keep the soil temperature more moderated.

Agree with the above but I water my garden every evening around 6:00pm if it has not rained during the day. We have sandy loam here in Metter, and my garden is nearly sand. I do not add anything but homemade compost to the soil, and I have not mulched. sure sounds like it sure could use some work.

Daily watering gets you water-dependent plants with watery flavored tomatoes and shallow roots. That is a stressful set of growing conditions.

I also have loamy fine sand for my soil. Tomatoes are fairly drought resistant plants. My tomatoes can go up to a week and not wilt. The problem I have is that watering my squashes cannot be easily separated from watering my tomatoes. I find that I have to water my squashes every other day or so or they will wilt and die. Mulch helps a lot.
