What is wrong with my tomato plants?
Hi! I'm growing some Roma tomatoes in a container (first time!) and the plants have recently started developing some spots on the lower leaves. I can not tell what it is, even with the many articles, they all look so similar! I would like to know if you can help me figure it out so that I can hopefully stop this from getting worse!
This looks like Septoria leaf spot.
Remove the leaves and dispose of them to avoid spreading this fungus.
