White veins in leaves

[HonoluluGirl]

Hi. My zucchini, yellow squash, and kabocha pumpkin plant leaves have white veins. What's causing this, and how do I fix it? Thanks!

This is my yellow squash:

I think these are examples of normal silvery vein patterning in these plants. They look very healthy to me, especially the last two.

The yellow squash, there's something off about it but I can't think what.

OMG I'm such a noob! Ha ha. Thanks, glad to know it's normal.
