Left you can se compaison of healthy plant vs ill one. Leaf oily shiny look. deformed, darker green as compared to healthy plant. Also stem darker green. No flowers ergo nofruits. Entire plant affected.

And what is your actual question? What the plant is, what the disease is, how to cure the disease, what the cause of the diseaese is, whether it's a disease at all or what else?

The question mark stands after disease. How you would cure it etc. without knowing what it is ?

Were the tomatoes fertilized with mineral fertilizers? Could it be ammonium sulfate?

No fertilizers. Plants are in pots (each in it's own) with same kind of substrate, organic, home made. All plants bought from same provider, same variety. It was like that from day one, different than the others.
Growth height is only a bit (almost unnoticable) less than healthy ones. Looks like not transmittable to other plants.

I guess if surplus of N would be a problem, it would grow much higher than the others.

It would be possible that different substrate batches were used in the plants. The sulfate in the ammonium sulfate hinders the uptake of Mg by the roots. Magnesium deficiency can initially be recognized by the yellow leaf tips, which later expand into necrosis.
In my opinion it is a nitrogen surplus with a simultaneous magnesium deficiency.
