Other 4 weeks or flowering week+ or week-, now the buds will form and then fatten up!
The best thing u can do is now buy a jewelers loop, to watch the thricomes, so you can know when the get cloudy and then start to flush and harvest when they start to turn amber. the white pistils on the buds will turn orange sooner, don't worry about that.
Hope to help and to be comprensive ✌️🏽💪🏼 Happy growing
