I wanted to ask if it's an auto because of your name, but I've never heard of an auto flower re vegging. Not an area I'm good with.i don't do autos. But from what I've researched they flower when they are ready regardless of photoperiod. Re vegging. Never even heard of this or it being possible. Only thing I could think Is stress ....but is that even possible? If it was hemp fields everywhere would re veg also, you would think.
Check your Genetics for sure. And you will have to move indoors under a timer at least. What's your weather looking like in the next 6-9 weeks. That's not conducive to a good growing environment . Your really late in the season. Can you go indoor? If not I fear your in a up hill battle. But I'll help with what I can.
