Purged plant of all nutrients for last seven days (clean water only). Many remaining fan leaves changed from yellow to purple. Plant does not respond well to heavy nutrient influx at the end of flowering. Next time will decrease the amount of nutrients going into the last few weeks. Some leaf tip burning was visible, but the nuggs were not harmed significantly during last few weeks. Very happy with this strain, and plant is currently upside down, and drying. Will give it seven days before trimming it off the plant for storage.
