didn't i cut my northern lights automatic too early ???

You decide when to harvest based on the trichomes you observe through your microscope. If you think they are ready to achieve the effect you want, then you haven't harvested too early. 🙂 This is personal for everyone; some prefer only milky trichomes. Others prefer a combination of milky with some amber. And some go for a more medicinal effect, where there is quite a bit of amber color. See what effect this brings, and if you'd prefer it differently, then you can harvest a bit later next time. Good luck! 🌱
