Leaves on zucchini plant turn crispy

Question

Within hours, some leaves on my zucchini plant turn from healthy to crisp. There are no bugs on the plants. I’ve used nutrient enriched soil when planting.

Answer 1

See if your leaves are similar to the one in this photo below. Their problem is due to overwatering.
