Trichomes not changing color

You shouldnt be worried - looks like youbhave another 2 weeks - most plants take longer than advertised but you are looking great for the week you are in, well done - patience is key now, it looks like nothing will happen for next few weeks but the pistils will go white to red / brown and the trichomes will turn - amber for couch lock and cloudy for head hype. More amber = more stoned. More cloudy = more energy, just dont cut tooo early or you wont be at peak strength.
