Yanking fans (not to be confused with YANKEES fans, who are misguided and like to overturn/torch cars) is not good at all.
When a cannabis plant loses a fan leaf, it's stressful, and the plant will try to replace it. In your case it has shot out a bunch of single-bladed leaves- HOWVER I have absolutely NEVER seen any that round.
WTF!! Thanks for the more pics, I am still going EEP! over them. That's just craziness!!!
