Will this work?

I would do a 3 node super crop bend at the height of hte rest of the plant. to make a even canopy. It will only set her back a few days healing. what you do is squeeze around the stem pinching it to crush and weaken it. Then once you get it a bit weak start to bend it back and forth and side to side. Do this in 3 locations close together, Then once they are all weak bend them evenly in the same direction until the whole top is completely sideways. Then tied down the middle and top( end ) of it. I think this would be best as you will be able to lower the light and get more intense light to all of the bud sites, which will give you more quality buds then having one top cob and a bunch of small buds. Happy Growing.

Yeah I wouldn’t worry too much. It looks like stretch is about done with. It shouldn’t get much taller, you can just bend that branch over to a 90 degree angle and it will continue to grow just fine like that. I’ve done it before in situations with limited room vertically

Awesome looking plant you have there. I wouldn't worry too much now... you could bend her back but your light does look like it has a great emitter angle to cover the whole space fully. She may have finished her stretch and thats as high as she goes...you may be ok with her like that. Good luck
