strange tomato leaves

[Vince G]

Has anyone seen tomatoes leaves going like this? As you can see the lower leaves are fine but suddenly the upper ones have gone thin and twisty. Any thoughts welcome

It is an Apero cherry tomato if that makes a difference. I have 10 plants in the polytunnel and this is the only one going like this. Same packet of seeds as last year, still well in date, and the plants were fine last year

I’ve had plants do that twisting of the leaves,I think it’s physiological leaf curl. I can’t remember about the effect on production but they do produce or I would’ve taken them out. I never removed the plants it happened to over the years,it’s not a disease that can be passed on to others. Let sideshoots grow as the leader if there’s a chance.
