Leaves curling inwards on tomato plants

Curly head

Hi All. I have 8 tomato plants growing in my tunnel. On 3 of them some of the leaves are curling inwards. They seem to be healthy otherwise n they aren't overwatered I think. The fruit is coming out on them. Anyone got any ideas as what may be wrong.
Thanks

Did you check for aphids? You can usually just squirt them with water and/or squeeze them with your fingers. A few ants on the plants could be a clue to aphids too as they feed on their sweet poo.

The aphids are usually hiding under the leaves and suck the sap out.

Checked and there doesn't appear to be anything on the leaves

Seems to be all over one n just the bottom of another. Most of them seem to be OK. I

They do this when very hot/stressed, do you find in the early morning that they are not/less curled in like this?
Not usually a problem , its when you see spotting or brownish discoloration that you need to take action (I've been experimenting with neem oil this year to control blight and other airborne nastys).
