Hi there Luna. So when the "mushrooms" / trichomes are clear that means they are empty, when they are milky,white that means they are full, when they are brown that means that they are oxidised/rusted and the molecules are degraded . That's why we say that the maximum potency/strength is when they are milky/white so you should try to harvest when there are no clear, all white, few amber for the maximum THC level. On average trichomes take 2 weeks to fully mature , but it can take longer and sometimes it can happen overnight, so you have to keep checking quite regularly. Just be patient, this is the hardest part. Hope this helps ! 🚀
