Leaves develop whitish spots and curling - what is this?
I have 16 tomato plants of various varieties in different locations and soils throughout my property. Every one of them is now looking like the enclosed photo in one stage or another (this is a more advanced case). These are the lowest leaves. New growth looks fine at the moment. I cannot find any evidence of insect pests. I cannot figure out what the problem is. The only commonality between them was the compost I used to start them in indoors, but this problem didn't start happening until 2+ weeks after they got outside.
Any help would be very appreciated!
