Hi all, I recently noticed these dark spots on my tomato plant leaves, and was wondering if it might be signs of some sort of fungal infection and if I should be treating them with something. The picture with the #1 is a Jet Star tomato plant and the picture with the #2 is a Sugar Plum tomato plant. I have been cutting the spotted leaves off, but was wondering if I should be doing something to treat them since the flower production for both plants seems to have gone down, mostly for the Jet Star tomato. I'd greatly appreciate the help, thank you so much!
