Is this plant in a container? Is it indoors? Has it possibly been exposed to a herbicide of any kind? Perhaps drift from a neighbors spray?

Tomato leaf roll (where the leaves roll up from side to side) is a physiological problem for plants that are stressed from some problem growing condition. It usually requires no treatment. It resolves itself.

But these leaves are curling backwards from what I can see (photo is blurry) and that is almost always a result of herbicide exposure.

If no chance of that and it is a container plant, how big is the container? The only other possible explanation I know of is that the container is too small and the plant is rootbound.

More info please. ;)

Just thought of something - check the undersides of the leaves for aphids. It is a possibility.

Thanks for answering. I only have one plant and it is in a 10 gallon container. It has been planted about 6 weeks and is inside the swimming pool screen. I have not used any pesticides or herbicides. I have been watering it a little each day. Thanks for your help

I forgot about the aphids. Did not see any.

Looks like drift from weed killer to me. If not from your side of the fence, perhaps from next door?

If you don't believe it is possible that the damage was from drift of a weed killer, then think about the plant's proximity to your swimming pool.

Is your pool maintained by a pool service company? If so, do they use any sort of product in a gas form? If so, the gas may be drifting onto your plant and causing the leaf rolling problems. I am thinking specifically of chlorine gas. Sometimes, though, the improper combination of other pool chemicals can cause a chemical reaction and release fumes that damage plants too.
