Tomato leaves curling/folding
 

One of the three tomato plants i have possibly has a problem or it may be thing with this variety. All the leaves appear to be slightly folded. The leave is kind of curled along the longitudinal axis, just slightly folded. All of the leaves are like that. Otherwise the plant is fine. Growth seems to be normal. It is green, flowering, and soon to set fruit. There are no bugs. Is this folding normal? Thanks.

Well if nothing else is wrong with the plant, that pretty much rules out tomato leaf curl virus. Is this plant the same cultivar as the other two?

The problem with tomato leaf curl is that once you rule out the viral cause, there are plenty of other potential causes that are difficult to rule out individually. In addition to the moisture management issue that AH suggested, I have had plenty of tomatoes that exhibit the longitudinal folding for a few days following a period of quickly-shifting weather patterns (e.g. high heat and aridity followed by a deluge of rain).

Hello ju1234,
How are the tomato plants looking now?
Are the roots healthy?
What is the air temp and humidity levels?
Are you using artificial light, or growing outside in natural sunlight?
What is the water temp?
Do you have any pictures of the plants and setup?

I found the answer to my question on web search. I had posted a reply with a link to the page where they showed all the different curling leaves of tomatoes. I guess the moderators did not allow that reply to be posted. Anyway, the curls i have is physiological. Thanks everyone.
