Lots of plants show brown/red hairs early in to flowering. it means nothing, it in no way means the plant is ready to be harvested. You want to look at the trichomes of the plant with a magnifier/ microscope to tell when its time.

You have 4 -6 more weeks to go most likely. FWIW there is no such thing as "Over Ripe" bud.

The CO2 tablets are nearly worthless, waste of money IMO.
