I attach two pictures, a general overview of the plants and a detailed picture of the most remarkable symptoms, white bumps in the nerves of tomato leaves, curved leaves, initial necrosis in the leave tips.
Growing conditions: 16h photoperiod, 25C, 75% RH, led lights (white+far red+UV), Hewitt nutrient solution (around 20 mL per plant per week), sterile sandy soil (gamma irradiated).
Dear Azcona,
from your picture I only guess. As far as I know, these symptoms are not most probably caused by any kind of biotic organisms. These symptoms are likely sourced by its genetic character, especially chlorotic bumps symptoms along the veins of leaf. Sometimes I met these symptoms on tomato leaves at our own studies in greenhouse. Rolling symptoms of leaves may be either damaging roots (mechanic damage), irregular irrigation or growing conditions.
I agree with Dr. Akbas in that, these symptoms are not most probably caused by any kind of biotic organisms,. From my point of view, i think it was due to a kind of "stress" and the plant excretes a hormone that accumulates on the leaves.

If, the lower side of the leavespots, looks like kind of a cristalline strukture, it might be due to a too high salinity level. Some capsicum-plants behave the same way.
