I think the upcoming 2 weeks your Girl will be done. and I look for the whole plant if i want to see when its time to harvest. But the Trichomes are in first Place.
Normally plant ishows discoloring leaves, yours is still green . Pstils should change ( on most strains they do) to orange // brown at least on 75 percent... On your Plant I see lots of white Pistils. And the trichomes, but i cant judge it for you.....because pictures alienate the true color of trichomes in relecting the light. So get a rtegular jewelrs loupe with light an look for cloudy trichomes.. there is no way around^^
