Hey Barbus, congrats on your very first grow, well done although not quite complete yet. I recommend ordering a magnifier to very the trichomes. Clear means not fully mature, milky is optimum and burnt glass looking will give you more of a couch lock effect but also you will start losing some THC value. If you are only going by eye then go by the breeder recommendation for amount of weeks in flowering and by the colour of your pistils. Start to flush at a ration of 70% orange to 30% white pistils. Thats not perfect but it should get you to harvest at an adequate time.
