This is the power plantplant and this is the northern light phenotype one with extra trichomespower plant and this is huge bud producing NL phenotype

Best way to tell I looking at your trichromes through a jewlers loupe , phone microscope, etc, I usually harvest at 10 to 20% Amber colored. More of a head, get things done feel than with More Amber colored, the more narcotic "couch lock" feel. They look close though. Good job on the girls

2-3 weeks+

Yeah check the trichomes and wait for 50% Amber. They look awesome great job
