DrJynx86answered grow question 5 years ago White hairs are the initial kind of, when budding is just starting, they need to get brown/black or entirely dissapear in some strains, the buds fatten up, trichomes fatten up and cover everything in sugar, and then depending on the strain maybe have some white hairs at the end before chopping time (like exploding from full calixes).
Probably 3-4 weeks more is a good estimation, and it's sure to get more trichomes, not less, so I would just keep on the same track, have some patience, and the result will be magnificent.
Good smokes!
