Broken branch on auto in flower. What should I expect

I tried taping but was wilting still 24 hours later. I noticed by trying to fix it I think I made it worse and was connected only by a sliver. Plant had no other training and left alone. It was a 3rd node secondary branch. I'll keep an eye for balls

if vascular tissue is still partially connected, try taping it back together and support it if necessary to take stress off the damaged area. Within a day or two it'll support itself again and be stronger than before. Leaves may wilt initially but should be fine the next day.. if they continue to look wilted, you may not be able to save the limb. pruning damage off is always an option too.. if the damage is too great sometimes there's no hope. I've seen some pretty major splits and snaps heal back together, though. if not severed completely, it is worth the effort. how bad will it set it back? if it was 1/5th of the plant you lost 1/5th of the growth... that's your setback. the plant will push on just fine at a similar growth rate as you had seen before relative to the environment you provide.

Depends on which branch, if one of mains or top, can force her into hermie in worst case, or allow some bacteria to enter plant. Tape wound with paper tape for a week. You will loose part of harvest, but if you do lst, try to utilize that empty space and redirect other packed branches a bit there. Do all training before watering, then plants not so crusty and dont break easy. Good luck !
