I've had this rosemary plant growing in my home for a few months, it's recently started to get this powder that looks like mildew on some of the needles... thoughts on how I could help it?

Looks like mealy bugs to me. First isolate the plant from all the others. Cut back a lot of the foliage, especially the parts covered in white. Spray the plant and the soil with a rubbing alcohol/water mix. Check for white on any other plant that was close or touching this one. Those little devils like to travel. Gene
