AUTOFLOWER STUCK IN PRE-FLOWER

I would maybe set your lights to 12/12 for a few days. Maybe she just needs a nudge to get fully into flowering. If she doesn’t start production of buds in a few days then put her outside for her flowering and let nature take over. Lol I know some photoperiod strains though will take 3+ weeks to finish stretch and start to grow real buds. I’ve also had some hybrids take on more of their sativa traits in some phenotypes and this will extend stretch and preflower as sativas tend to take much longer to flower and stretch more as well. Could just be this happening too. Honestly though I don’t mess with autos to much so this is only an educated guess.... lol hope it helps ya maybe though, cheers 💨
