So I have three tomato plants on my balcony, two Sweet Millions and one Sweet 100. One of the Sweet Millions (in its own pot, but between the other two) has suddenly gotten brown spots on many of its leave. This has not happened to either of the other plants right next to it. I live in the Seattle area, where it has been an unusually cool spring (almost every day in the 50s). This is baffling me, as it is only one plant. The affected branches were on the bottom, though one upper leaf branch looks like it is getting affected from the farthest out leaf, working towards the center. Should is toss this plant? It is otherwise growing very well.
