Last fall I murdered my lawn with roundup, roto-tilled it and had it
smoothed out by a rock hound. I planted a mix of blue grass, fesque, and
perenial rye that is the house blend from a local lawn and garden store.
It's been fertilized with 10-10-10 and well watered and for the most part
the lawn is absolutely beautiful. BUT, there are some spots that are thin
and the grass is not lush like the rest of the lawn. I'm not sure what to
do here. Some suggestions please, this is in SE PA.

Are they large areas? If not you could top-dress and re-seed.
