Is this Knemidokoptes?

I am no professional, but if you suspect scaly face/leg (Knemidokoptes), visit your avian vet ASAP! To me it looks like a possibility, and if caught early enough it is very easy to treat.

Welcome to the forums, sorry your first post is one of a health concern.
I had to Google the term and found an older thread: http://www.parrotforums.com/budgies-parakeets/25158-how-avoid-budgies-knemidokoptes-mites.html

Also this: Scaly Mite in Budgerigars

I highly recommend a visit to an avian certified vet for evaluation and treatment. If none is available in your area, perhaps a vet specializing in falconry, or a zoo?

Please keep us updated!
