They're putting on lots of new growth, but they've also now got a lot of powdery mildew. Any ideas for getting rid of the mildew? Is there a spray that is human/pet-safe?

Thank you!
Mildew is often worse when the roots are dry. See if you can move them to somewhere cooler, pinch out the tops, possibly repot them, and don't let them dry out.
