This bubba is gonna keep stretching for a while, I wouldn't be surprised if it became huge. Seems you have a cool pheno though : yours is getting purple strongly and early, usually that actually happens later. So you might have a mutant bubba kush on your hands, You're already SCROGing so at this point all you can do is pray really. Later on if and when you have to make a decision you can kind of bend the stem so the flowers keep growing but at an angle just use some duct tape as a bandage on the damaged part of the stem, wierd but it works ! This is gonna be a cool pheno to follow ! good luck 🚀
