The stretch is strain, phenotype, and environmentally effected. For instance, a lanky tropical sativa would tend to stretch, this type of natural structure can help increase airflow and prevent molds. Whereas another phenotype of the same strain might not have as much of a stretch, which would be an ideal phenotype for trying to keep the plant from going over the fence-line. Another factor that could cause a lot of stretching is being next to the wall. As the sun travels through the sky, day by day, there will be an angle for the shadow, where the plant slowly gets shadowed on its upper growth. The limbs may certainly reach for the sky to try to catch the last bit of rays before the shade comes. So it's certainly possible that the plant, by the time is done growing in Fall, will be very close to the wall-line.
Unless the plant is a very stable autoflower strain, it is going to vegetate all summer and flower in fall and be ready for a harvest in September/October (ideally), since we are getting so close to the Summer solstice in June, and there is no way in hell she would have a chance in finishing flowering before then. She will either go into a small revegetation (which a lot of the times can go unnoticed because the plant just hadn't built up a ton of flowering hormones for it to make a huge difference). So I would say to hope she does not start flowering until sometime in August because that will provide the most of the best, highest quality flowers. I don't see a need to keep picking this plant to the bone, let her be for a while. Just water her and let her grow with the occasional sea-kelp mist. Restrain flexible new growth if possible, but don't take a chance on snapping off woody fibrous growth, it's just not worth it. Even if the growth hardly gets any sun, it can still provide valuable energy to the plant, continually wounding a wounded plant that is still recovering is only going to lower brix levels, which will lower her immune system even more.
I usually only reserve defoliating for the absolute most healthy, vigorous, and hardy specimens that I give the analogy is like trying to control a wild beard, you keep shaving it and shaving it, and it just grows back bigger, better and stronger. I don't see this being the case. She just needs some down-time. The trick is not over-watering at this point, if you can get her to drink her water in a balanced manner, she will metabolize her nutrients better, and infact you will see bigger and better harvests when watering is done correctly.
Just my two cents 'n all.
lookin' good GF, those will be great fluxies!
