if you use a clean blade or scissor to do it it should be fine. But you will need to leave it for a couple weeks to heel before flowering - when i did it to one of mine black sap game out to heel its wounds but ended up fine. The end result wasnt worth it though just 2 medium sized buds aposed to one big one which id prefer. So if i were you id tie her dow, just put a bit of string on her stem and pull it down gently and she will start to bend then tie the string to the pot of a brick or something - she will then grow up again you can either leave her to do that so she just has a curve or pull it back down again and grow her out in a corner shape - but that depends on your light space etc. hope this gave u couple ideas
