Cómo veo que mi planta entre en la flora?

You can't judge harvest time by the pistils. You should get a 30x or 60x magnifying glass to monitor your trichomes. The trichomes start out as clear and when they get milky and cloudy they are at their maximum thx level. They turn amber when the thc starts converting to cbd and other less desirable chemicals. I flush when I start seeing amber color. Good luck with your grows!
