I agree with Hugo, I find trichomes color to be misleading. Some strains never really amber up in color.
No white hairs and quite frankly as Hugo pointed out it should "look" done. Should be swollen likes it's about to pop.
It looks very similar to a purple diesel I used to grow.
Also, if this is your first grow, you blew my first grow right out of the water (probably most of the other people on here too ). That is a VERY, VERY GOOD first grow! You should be proud.
