I just bought some tomato plants from the local nursery(not a big box store). I planted them in larger containers last Sunday. Yesterday this plant started to droop, so I thought it was a sign it needed some water. I put some in, I don't think I put too much. Today these gray areas started to show up in the middle of the leaves. I have never seen this before. I have also been pinching off some leaves that have gone bad and that is the picture included. They are showing up on the bottom set of leaves. Can I just take those branches off? Any help would be appreciated, I do not want to lose these things so quickly..
