Hey… I got this on my tomato leaves. I had the same seedlings in two different greenhouses. In the first one, they are all healthy, but in the second greenhouse, some of the leaves turned out like this. I think it was caused by some kind of pest, but I’m not sure. I used Mospilan on it, and the new leaves look fine. If it was caused by insects, do you know what kind might have done that?
