Outdoor in ground 5% Amber Trichomes first grow

The last feeding was 9/14 I notices just 1 or 2 off colored trichomes yesterday now is obviuous about 5% amber.
This is a hybrid “Plushberry” being 80% indica.
So if the Trichomes are at 20-30% amber 9-11 days into flush, is it ok to harvest?
Thanks everyone!
