Grey patches on the edge of cucurbit leaves

yirmahmJuly 6, 2010

My butternut squash, pumpkin, and cucumber plants all have grey patches on the edges of some leaves. The spots sometimes appear in the middle of leaves, but seemed to be more concentrated on the outside. The plants are generally healthy (dark green, increasing in leaf number, setting flowers) otherwise.

Could be a bit of drought stress..... I would also turn the leaves over to see if there are mites or leaf hoppers.
