You might be right. When I wasn't pushing them this hard, they would have HINTS of these issues. Ever since I pushed my light intensity and made these girls work HARD they've become more noticeable. I think I have an idea on how to cut back on having as much, but it's at the expense of WEIGHT!I bet you its that strain. Cookies was made via accidentally pollination. It was made via hermies and they ended up with a huge bach of seeded weed. Those genetics weren't deigned and made by a proper breeder but a amature. Did you hear about their purple rain they put out made from the same genetics, they were a mess. Loads of sterile seeds, mutants and bad hermie and inbreeding issues. Those hermie bits are developing inside and probably always have been on the strain deep in the buds or tiny bits you cant normaly detect. They probably get worse when your pushing the plant too hard. All those cookies and gelato strains can have issues. Id go as far as saying many strains going round today can have issues as many are made and based on hermi pollinated bag seeds and from using unstress tested females ect. You must of herd how people have been finding seed in many of these strains today, its cause they haven't been made properly and then are continuedly used for breeding when they need to be fixed before use or not used to cause further damage.
