What causes tomato plant leaves to curl up?

Watering your tomato plants properly is the key to tomato success. Too much water and the plants drown—too little could cause blossom end rot, when the tomatoes turn black on the bottoms. Inconsistent watering can also cause blossom end rot, split tomatoes, and stressed plants.
Can tomatoes recover from leaf curl?
As long as there are other growing points remaining, the plant can recover, and the leaf curling will only be a temporary observation.
Should I cut off curled tomato leaves?

How do you fix curling leaves?
CAUSE: Heat stress causes rapid evaporation, so plants curl up to conserve moisture. Plants too close to high-intensity lights are prone to heat stress, but it can be a problem in any room where temperatures are persistently above 80 degrees F.

What does herbicide drift look like on tomato plants?
Tomatoes are very sensitive to 2,4-D (see above photo), with injury from herbicide drift usually occurring in May and June. Leaves become twisted, curled, and strappy and stay small in size. Injury is observed on the youngest leaves. Plants rarely outgrow the injury caused by this growth regulator.
