Hello, I have a 9 and a half month old photo period plant, grown from a seed. It's my first photo period, I have grown 1 auto flower prior. Indoor grow. Anyway, I have an issue with Flipping the plant to flowering. I have tried switching from 18/6 to 12/12, then after a month I tried 42 hours of darkness. She stretched 4-5 inches vertical but after 3 weeks, no signs of pre flowering. Does anyone have any suggestions? The plant has a bit of history, at 4 months i tried to flip but she developed a problem with yellow leaves with brown spots. I transplanted from a 3 gallon fabric to a 5 gallon fabric with a flush. I adjusted nutrients and figured out the yellow leaves issue, she had lost too much mass, so I flipped her back to 18/6 for additional growth. Now she is healthy and happy. Flipped again, waited 3 weeks and no changes. Tried the 42 hours of darkness, she stretched but after 3 weeks, happy plant nothing else. Please help, eventually she will out grow the tent space and it would be nice to transition to flowering. I have pictures on my phone, but don't know how to insert them.
