Help needed

Chrissy the gardener

i don’t know if you can see the leaves enough to help but thought I would try anyway,
my tomatoes are being grown in the greenhouse and the new leaves on the top are deformed and rather spindle can’t see any bugs on them so not sure what to do to rescue the plants,

They have green fly and with basil in there there may be white fly, it’s a WF magnet! 
Have a look under the leaves and see if there are any.
could be just heat stress, they do curl up when they’re hot.
