White fuzzy stuff

[angelaaloisio]

I have not watered my phals for long time about a 4-6 weeks I imagine. The leaves are still green, no blooms since last year, but there is some sort of white fuzzy stuff on tips where blooms would come in if it was blooming. I would describe as like something between a caterpillar cocoon and a powdery mildew consistence like you would see on roses. Any ideas what this is or if bad for plant.
