Curly leaves can be caused by draughts. But your photo also shows dark leaf stems at the top of the plant - this may be caused by blight, but could also be caused by a period of chilly temperatures. Can you see any dark 'bruises' on the main stem? (this would likely confirm blight) Are they being grown inside or outdoors?

Hi hi thanks for reply. The Tomatoes are grown outside in a cold frame. Just had to get a taller one as tops were exposed to wind . Now enclosed. New to this so just feeling my way . Photo was taken inside while I put new cold frame in place. 👍🙏
Let's hope it was just a chilly wind. Keep an eye out though for black bruises on the main stem and leaf stalks which indicate blight. I've had several warnings recently from blightwatch that conditions are good for blight where I live. Hope you get a good crop
