You may be OK I’ve done that and they heal up in a matter of days if left alone. Hey you may just increase the potency for that plant. Some do things like running a chopstick or dowel right through the main stem. The theory is that the plant puts out THC when distressed. Ice water flush pre harvest is another. Actually “super cropping” is breaking the stem internally while leaving the stem walls in tack…same distress theory = more THC etc…
If its taped back in place real good and sealed from air it should keep right on going like it never happened. I use teflon tape and wrap it like an ace bandage. A little honey or aloe helps if you have some close by.
Let us know how it goes. Im sure I’ll eventually end up in a similar situation.
Also, some folks recommend silica to strengthen branches to support big flowers. Are you feeding Silica? Thoughts on that?
