Expert Response
Tomato plants do tend to get diseases. I am giving you a link. For now, cut off the lower leaves and any infected leaves. Clean your pruner and hands/gloves to avoid spreading it. Place a mulch under your plant to prevent soil borne fungi splashing up. Even glass clippings will work. https://extension.umn.edu/plant-diseases/tomato-leaf-spot-diseases
