How close are your pumpkins ready to be harvested?

Lorri D, I planted pumpkins later than normal. My other pumpkin plant has fruits that are just beginning to turn. The pumpkins on this plant are still green and not growing, although they seem healthy, just stunted. But the leaves appeared with this brownish veining almost overnight. Have been spraying both plants for downy mildew....it almost looks like this could be a nutrient deficiency but why in only the one plant???

Could be more than one pathogen, hard to say which looking at pictures.
