Where do you see 3 wks?.
I Highly doubt her trichomes are that far away pal.
She looks ripe as she is.
You really need trichomes check. To harvest of look/pistils, well. That's a mistake. Yes. You can judge it if she looks ripe and is as far along into flowering as she is rated for my the breeder.
But, personally. Without knowing her trichomes. Just by looking. Id throw her into a flush if you've been using heavy synthetic nutrients. If Oraganic she's ready harvestable.
Also without looking at diary its even more of a guess
