Thanks for posting those pics, very good. After looking at them, I wonder if
the lesions that look like early blight might rather be necrosis of another
kind. The interveinal chlorosis looks like it could be a sign of nutrient
deficiency. You might consider sending some tissue samples to a testing lab
to see if anything is lacking. A&L Labs has sites in the Midwest that could
do the tissue tesing. Their website may be of help in determining tissue to
take and how to ship it.

One fellow at Kansas State University you might want to contact is Ted Carey.
Ted is a good guy who specializes in High Tunnels. His University website
