I am new to this forum, as of today. I am new to gardening as well and was going off of advice from Home Depot. My tomato plant is in need of help. All was going good and then it seems in the matter of a week, leaves starting turning yellow, wilting and then healthy green leaves starting to form small black spots. I only have one tomato on the plant which is still green and just smaller than a golf ball, but the bottom of it didn't form right and it almost looks like a crack along it. We just had a lot of rain and temps have been in the 50's to 60's. This is a "beefmaster" tomato plant, as listed at Home Depot.
