Broken branch on auto plant

You've done what needed to be done after brocking the stem. ^^ After healing, it should be stronger and would not have impact on yield. But don't forget to remove the tape as soon you see the branch healed and getting bigger.

No worries, my friend, in the next few days a small knuckle will form that will strengthen that broken branch, and it won't affect the yield at all. If it didn't break the branch into 2 parts, it will recover. The technique of cracking branches is called cropping, and it's a technique that's not quite like pruning but could be similar because if you do it on all the branches, the plant experiences stress. But just one branch is no big deal. Happy growing!
