The last few days I've noticed some of the leaves on my pumpkins are turning yellow and dying. At first it was just some of the older, smaller leaves near the base of the plant, but now some leaves farther up the stem are yellowing too.
We've had a heatwave the last few days, so they have experience some sun wilt recently. The only fertilization done lately was some urine which I focused on some nearby corn.
What does it sound like to you guys?
