burned tomato leaves?

Tomato   

Hello, my tomato plant's leaves turned like this from one day to another, what is it for? They look like if they have been burned and I don't think is because of the sun because it hasn't been so hot here and because there is another tomato plant next to it and is totally fine. Also some of the leaves are curled, I think is normal but if it is not please let me know. Thank you!

I suspect thrips. Try holding a piece of white paper directly under an affected leaf and tapping it (the leaf). If I'm right, you should see tiny black insects fall onto the paper.

It looks similar to nitrogen burn. Have you been heavily fertilizing the plants?

Fertilizer Burn. Especially seeing that the leaves are curled - mostly due to excess Nitrogen. Use some MgS04 aka Epsom Salts as an alternate fetriliser rather than just one type contianing nitrogen. Also, a little more dilute fertiliser mix would be beneficial especially if you drench the container a few times with it to wash out excess salts and replace with new nutrients.
