unlucky mate, did this once with a pineapple chunk, it never really recovered from that, still flowered, but just lost it's vigour, doubt the tape will work, but is worth a go i guess :/
Treat it like you would a broken leg wrapped it up well then find some popsicale sticks and make some splints. This should help you save the broken limb.
Looks like a bad one to me.
Im also attempting a SCROG these days and thats one of the things Im afraid to see happening.
Im really clumsy. Cant say what will happen in Your case, but I hope it goes well.
I dont know if this would work I will some looking around and if I find something I will repost here. But fellow RIU'ers what would happen if you took some kind of rooting hormone or like B1 thrive or some similar to air layering I know thats to clone but if all else feels at least you have a clone!!!
i've supercropped plants and accidentally ended up exactly what is pictured. but i did it earlier in the grow. believe it or not...just splint the mother fucker and it will form a callus. valuable lesson for you on supercropping and the amazing ability the plant has to fix what you fucked up. splint and learn
