Is it ready?

Hi, Can anyone help me to tell if my plant is ready to harvest. I have 3 white russian plants that have been budding for 68 days. I have been checking the trichs. every couple of days now. They are cloudy but not turned amber yet. Should I keep them growing? Seems like 68 days should be long enough. I just want to be sure.

cant really tell with those pics, you will need a better microscope. i use 60x - 100x
