It would help to know strain type, how long it's been in flower, etc. Also, do you have a Jewelers Loupe? It's best to see the trichomes to know if it's ready to harvest or not. I prefer phone lenses (add on kind). See my pic of my trichomes from day 58 of flower, Aurora Indica Fem. You can see that most of them (trichomes) are still clear and glassy looking. Some are cloudy, plastic looking, but I have a couple weeks to go still. But I watch them daily just in case.
