sativas can go up to 13 weeks. but it is a bagseed so you cant know that. so let her go for as long as she can and harverst when the trichomes are ready. Dont judge by the bud-size/mass. She will get much bigger than this, believe me. First browning of the hairs is a sighn to tell you she is maturing so you can reduse feeding and start flushing, but she cant exactly tell you when she is ready for the axe, only trichomes can tell you that. So be patient, and good luck! Your plants are helthy and you will have great yields if you do it right. Dont forget to flush!!! :thumbsup:
