I've noticed some peculiar spots on the leaves of my tomato plants, and I'm worried it might be a disease. The spots are yellowish with a darker border, and they're primarily on the lower leaves. The plants are in raised beds with well-draining soil, and I try to water them at the base to avoid wetting the leaves. They're getting plenty of sunlight and I fertilize them regularly. Could this be early blight, or is it something else? What are some effective treatments or preventative measures to take? Any advice would be greatly appreciated, especially from those who've dealt with this before. Thanks!
