Tomato problem

turmeric

Hello, has anyone any idea what may have caused all 9 of my tomato plant's leaves to curl up really tight and go hard?  It's started at the top of all of the plants.  Fresh growbags, no weedkillers sprayed anywhere closeby and they're in a ventilated greenhouse.  Many thanks.

Any sign of aphids or other little creatures inside the curls?

Yup, looks like could be insect damage....have a close check as they could be very very small -like mites

Could be one of the 20 viruses that affect tomatoes, causing a wide variety of mosaic patterns and distortions to the leaves, stunted growth and marbling patterns on the fruit, whenever the plants are growing from late winter until early autumn.

Although Stunting, distortion and fern leaf may also be caused by exposure to hormone weedkillers, to which tomatoes are very sensitive. These are volatile and can act from a distance, without direct contact. Providing the source is removed, plants usually recover, but they do not usually recover from virus infection.

I know you say weedkillers have not been near but have you used any lately when the green house was open ( blown in on the wind) used and not washed your hands / gloves or used near the same watering equipment?

I had a greenhouse full of tomatoes of different varieties last year and just one plant( a beef tomato) suffered this strange contorted growth. Continued to grow as normal afterwards,  but the fruit that ripened at that point was a huge misshapen thing.

Thank you to everyone.  I did check the distorted leaves for insects (mites or caterpillars) but really couldn't see anything at all.  Perhaps they had moved on?  There was a tiny amount of slug or snail slime but I had presumed that the slugs or snails had arrived after the damage and taken advantage of a sick plant?
Hampshire Hog, my weed and feed for the lawn is in a bag within a box that's sealed but it is in the same greenhouse, are they really that susceptible?  I certainly haven't used weedkiller and then touched all of the tomatoes so it would have to have got to them through the air but I didn't realise they were that vulnerable.
Many thanks to everyone though for your suggestions.

@turmeric Yes they really are very susceptible along with other plants and lawn weed and feed is a hormone based weed killer so that may well be your problem I would very carefully move it out ASAP.

Thanks Hampshire Hog (I like your quote at the bottom of your message too, made me smile).
