Well Sunshine,

Nobody can give you an exact day to got and cut them down. Your girls should be closely examined with microscope to view the color of the crystals. Most will tell you if fifty or sixty percent are turning brown then you can cut the plant. I usually say take samples since the high is different at different times of the harvest. You may discovery the high is better at different times of the harverst compared to others. Since your outdoors you may not wish to keep visiting the site for security reasons. Maybe a couple close up pictures could help us give you a more accurate recommendation.
