Ot: squash leaves

I'm new to this garden thing. I know some of y'all do it or I wouldn't post this here. My leaves on some of my plants are turning a white grayish color. Is that ok?

These are zucchini

    Are you watering with nutrients? If so, are you following prescribed amounts and or using them every watering? 

    If yes I would use just water for in between feeding.  Maybe check PH as well.

    No just water. They are in raised beds with some garden soil mixed in.

    That's what my father in law said, but haven't used anything on them. I bought a couple bags of garden soil and mixed it in with the dirt in my yard and filled raised beds.

    I looked through my Southern Living Gardening book. This looks like Powdery Mildew. I have quoted the section from the book for common squash issues. If none of this helps, I usually email Walter Reeves "The Georgia Gardener" from his website.

    "For all types of squash, the most serious pest is squash vine borer, a large white caterpillar that tunnels through stems, causing vines to wilt and die. Squash bugs are another possible pest; they suck plant juices, causing stems to blacken and wilt. To control both pests, plant under floating row covers, or dust or spray the base of the plants with rotenone or carbaryl (Sevin) every 7 to 10 days during the growing season. Squash bugs lay yellowish to brown egg clusters on the undersides of leaves; look for these and destroy them. You can also spray the undersides of leaves with rotenone or insecticidal soap.
    The most common disease affecting squash is powdery mildew on the foliage; to discourage it, plant in full sun, maintain good air circulation around plants, avoid wetting the foliage, and remove infected leaves as soon as you see them. Neem oil and antitranspirants can also be effective."

    SWMBO has the green thumb around here. To optimize water use and keep the foliage from getting wet, she runs a soaker hose through the beds and hooks it up to a timer on one of the yard faucets. Saves on the water bill and the water gets to the roots where plants need it the most. She also lays straw down in the beds to keep weeds out and help with water retention.
