Hi everyone. Great to be on the forum.
I grow and give way tomatoes to about 20 people each year. I'm worried about this year's crop which have been growing under lights in my basement. It's been cool and they probably have been a little too damp at times.
I know the purple means potassium deficient. But they are also getting thin papery leaves with pock marks on top. The leaves curl and the lower branches die and fall off. The underside is scabby. Here are some pictures:
Any help you might offer would be very much appreciated.
Is it a bacterial infection?
Thank you.
