I don’t think my popcorn safe for the birds 😟

After last week's heavy rains several days in a row and chilly nights, I noticed the plants not looking pretty anymore. I thought maybe it's just the natural drying process but yesterday I noticed the spots on them which I'm guessing is some kind of disease 😟

What do you think of is?

It was still fun trying.

I'm in NYC Zone 7B. It's my 1st season growing anything.
