My butternut squash plants, although are growing very well, seem to have this white patterning along the veins of their leaves.
It looks a bit like powdery mildew, however all of the pictures I’ve seen of that online seem to be more spotty and less distributed like this. This patterning is seen across ALL of my squash plants and I’m not sure if I need to do something or just let it grow!
Not powdery mildew. I think some varieties of squash are just variegated like this.
Bingo. I've grown a similar verity over the past few years and the first year I was very confused.
