Nah these leaves turned yellow before I even added nutes, It seemed to be a PH problem, ever since I added PH down everything is growing out green. I exaggerated a bit, I would say it was more of a strong buzz that lasted a good 90 minutes. I am new to growing and wasn't aware of leaves producing THC but I read a Marijuana growing article and it says that leaves can have alot of THC sometimes and the plant begins producing THC very early.
