Does My Plant Have Powdery Mildew?

I got this Kimberly Queen fern recently. I’ve been misting it a couple times a day because my house is pretty dry and I don’t want to have a humidifier running all the time. I noticed this white powder on the older leaves; is it powdery mildew, or is the plant just dirty?

It does look like powdery mildew. Hold off on the misting for awhile and see if that helps. Then, instead of misting, try a pebble tray.
