What’s wrong with my tomato plants?

Hi,

This is the second year this happens. I have changed everything I could possibly control multiple times and it still keeps happening. Last year the plants I kept either grew a new growth that was curled or new growth that developed normally. It only affects few varieties, but these are different from previous year too. I have changed the producers of seeds as well. I have checked guidelines and everything leads to herbicide damage, which is also impossible as no one has been doing anything with herbicide nearby. Same applies to insecticide. The main stem looks like someone has hit it with a shovel lol. No other visible sign besides the curling and stunted main growth. Unfortunately I haven't taken any pictures of it last year. What am I dealing with?

And before anyone suggests yes I also changed containers and threw away anything that could possibly be affected from last year.
