im positive that they arent sacks. they are female flowers. they look just the same as all my other female flowers, except no white hairs shooting out of them. positive they arent hermies, the plants are in excellent condition, and are clones of clones of clones(etc) of a widow going back over five years. I was thinking more of a mutation, or possibly my light burnt them? Or maybe some other problem...room temp is 78 with lights out and a high of 85 with lights on. 20 percent constant humidity. advanced nutes line, currently feeding connoisseur, voodoo juice, carboload, hygrozyme, and big bud. ph is 6-7. no signs of any deficiencies or nute burn. so I'm completely stumped :[ thanks for your advice though
