I've noticed several of my tomatoes have some yellowing to their leaves. This one is by far the worst. It's my first time growing tomatoes and I'm concerned it could be leaf spot or some sort of blight?
They were planted 3/19, transplanted on 4/21. They are under T8s on a 16/8 schedule and given 1/4 strength liquid fertilizer every 10 days. Any help is really appreciated!
