Ich bin mir ziemlich sicher, dass es kein Mehltau ist, was die einzige Antwort ist, die ich beim Googeln bekomme. Korrigieren Sie mich, wenn ich falsch liege. Die Blätter, die weiß waren, waren von Anfang an weiß.
Ich baue es an, um die Blätter zu essen, deshalb mache ich mir ein wenig Sorgen.

Pumpkin leaves white maybe other reason- google good explain reason:
Sunscald: Direct, intense sun can scorch leaves, turning them white or bleached.
Solution: Provide some shade if possible, or ensure plants aren’t in a spot that suddenly gets harsh afternoon sun.
Nutrient Deficiency: Lack of nitrogen, iron, or magnesium can cause discoloration.
Solution: Use a balanced fertilizer or a liquid feed.
Overwatering: Can lead to root issues, causing yellowing or whitening leaves.
Solution: Water deeply but infrequently, allowing soil to dry slightly between waterings, and ensure good drainage.
Pests: Spider mites or mealybugs can cause damage that appears as white spots.
Solution: Inspect undersides of leaves for tiny insects; treat with insecticidal soap if found.
Some leaves are just variegated like that.
There are white spots on the leaves that are normal. You also have a powdery mildew problem tho. Just cut the affected leaves.
Idk man, looks like powdery mildew to me. 🤷♀️
I agree, that doesn’t look like powdery mildew. Powdery mildew is more blotchy. My best guess is silver leaf [https://plantpath.ifas.ufl.edu/u-scout/cucurbit/silver-leaf.html](https://plantpath.ifas.ufl.edu/u-scout/cucurbit/silver-leaf.html) but I have no personal experience with it.
That’s pm, powdery mildew
