All very good points, I'm not saying cut the leaf in half though that would be ridiculous, I'm talking about a quarter of an inch, that little tip . According to him that part of the leaf does nothing so the plant not only doesn't miss it but actually is happy that It's gone. No facts to back it up but its something he picked up and "saw a results" with so he does this routinely. I do always sterilize the scissors first and for some reason feel very comfortable doing it and I don't touch a plant unless I have to like bending leaves so light can get to bud sites or taking dead yellow leaves off the bottom that's it, I'm not one of those people that's handsy with them now I'm stoned babbling lol
