I had the same problem. I guess I had a light leak when the door was shut with lights out and caused this plant to reveg. From what I’ve read it can take several weeks for it to go back to all out flowering so I’m planning on adding around 4 to 6 weeks on this plant. This plant is 5 weeks on 12/12, and 10 days since I fixed the light leak. I’m planning on at least 7 more weeks, and I’m still not sure it’ll turn out worth a shit. Not sure if this helps you, or not.
