Why are my tomato plant leaves curling?

Anyone know why my tomato plant leaves are curling?
It can be caused by wind damage, over watering, under watering, severe pruning, too early transplanting, OR it can be viral. If you have more than one plant and none of the others are exhibiting it it could be that this variety is just more sensitive. If you've been having cool temperatures and then suddenly really hot temperatures that could have done it, or it could be over fertilized or not have enough nutrients. You need to think in depth about how you've treated the plant, and if you have others what they look like. If you think it's over watering, cut back for a few days. If you haven't fertilized, maybe it's time. I also heard that adding a calcium supplement can help with some tomato issues, like blossom end rot. I have buried a Tums antacid in the dirt near each of my plants just to see because last year we got to blossom end rot.

I do have one tomato plant with leaves curling this year (and all of the others are growing fine. I believe it was severely damaged at the early stage just after transplanting. A 🐿️ or πŸ‡ or 🐦 broke it off. It's never quite gained back a healthy look. It may never fruit. If it doesn't flower soon, I'll be pulling it up so it can become fertilizer🫣
Hey Erica, if the weather has been extremely hot where you’re at, you’re going to want to water it more. typically early in the morning and than again in the midday. I’ve been finding myself watering for 20-30 min lately, because we haven’t been getting any rain.
It has blooms, been rather dry lately but got rain a day or two ago, I’ll just watch it. Sounds like too many variables can cause this
@RefulgentPinoak do you mind me asking what your watering routine is?
A lot of times curled tomato leaves are signs of stress. Inconsistent/not enough watering, sun/heat, fertilizer. etc. They need a well balanced fertilizer, one that is too high in nitrogen will curl leaves, as well will, high temperatures. If you are in the part of the country with abnormally high temps, that could be the culprit. If they are in ground they should be getting at least 2” of water per week. Always base water, if possible. There is also a disease caused by leafhoppers, known as Curly top virus, that can curl the leaves. Do they seem thick/leathery? If so, that might be the problem. Unfortunately, if they get that disease it is best to pull them up πŸ₯² to keep from contaminating your other plants. Hope this helps a little.
@Vjunc about every other day if no rain, slow stream about 10-15 minutes depending on if water stands quickly or drains well. Raised beds..,in Missouri by the way
Also been 90s here with little to no rain
@RefulgentPinoak try watering daily and see if that helps, I’m only thinking it needs more water because from the photo you posted your tomato plant looks very healthy.
@RefulgentPinoak right? Too many variables for sure!

I hope despite this development, you have an abundance of juicy tomaters in the next month! Where in MO? I am in IL just south of St. Louis.
