Pink Brandywine leaf disease
Attached find a file showing diseased leaves on a Pink Brandywine heirloom. The leaves affected are all on the lower part of the plant. Was hoping someone would identify this problem, and suggest effective solutions. The problem (thus far) does not appear to be spreading rapidly--the rest of the plant looks in really good shape (as of this writing).
Thanks much for your assist and feedback here. BTW: our zip code is 39837.

The problem described above as well as the pictures appear to be characteristic of a magnesium deficiency. I would recommend taking a soil sample and work with your local agent to determine the source of the deficiency. It may be induced by low pH or other environmental conditions. Our office in Colquitt is on 406 West Crawford Street and is west of Franklin's Spring Creek Ford. I look forward to hearing from you soon.
