i am growing purps right now, the leaves and stems are purple, just as if it was cold out at night. i have been tearing my hair out trying to find why it is purple (calcium? maganese? magnesium, whatever?), now i know it is due to the strain...............PURPS! bought the seeds called purps, should have found out more, i would not have lost so much sleep, lol......the buds on them do smell citrus like...kinda almost like dove green soap. Cant wait to harvest, cure, and smoke......yummy.
