It's not that common but it happens , it happened 3 or 4 time furing the last 3 years for me. The last time was with a Cream cookies from fast buds which grown like if I have toped her twice. Take advantage of that genetic trait to apply some LST method or to do it easier
It’s seems pretty rare on its on own but I was lucky enough to have one split on my g-14’s we just harvested it’s pretty sweet! You got a gem 💎 Good luck 👍🍀 with your harvest! 💯
