Plants suddenly going downhill
My plants are dying from the top. The leaves are turning yellow, dying, have large brown discoloration on a large part of each leaf, and the stems are falling off.
Below is a picture of one of the plants. If this is an untreatable systemic disease there's nothing to be done. Perhaps it's early blight which is treatable? Or maybe it's environmental.
I've dealt with late blight before but this is nothing like that. It's happened much earlier in the season and suddenly. The plants have been in the ground for almost 3 weeks. I have several different varieties and they all look about the same--Better Boy, Early Girl, Celebrity. etc.
I have more pictures which I'll send along.
