Transplanted 12 of these plants on May 3rd into a raised bed. Sweet Corn variety of some sort that I purchased from HD and started as seedlings indoors in March. They were growing great since May 3rd and now Iv'e been noticing a slowing growth with some sort of possible leaf fungus on all of them, some more, some less. Trying to figure out what it is(maybe blight?) and how to stop it! I'm in Zone 7, LI NY. We have had some hot, humid and rainy days over the last week. Any advice could help!
