This is my first year growing tomatoes and I am new to all things that come with it. The plants seem to be growing just fine, but I have noticed several spots on the leaves that are concerning me. I am getting a lot of different results just searching the internet for an answer so I thought I'd look to fellow gardeners for help. These are showing up all over the plant, including the newest branches at the top of the plant. What are they and what can I do to fix this?
