there are several variables but yes you can box cut them,take them off at the stem with clippers or just thumb n forefinger pinch off n cut with thumb nail.and it will slow her down a couple days here n there each time you do it so you never want to remove more than a few every severl days.and thats only if your willing to have it go a bit longer cuz it slows growth.better growing conditions n stuff like that lessen said stresses,but if you flat out trim her up n pull a bunch n stuff you'll shock n stunt the crap outta her man.so the best thing I can tell you f your planning on doing anything like that is to not pull more than four leaves at any one sitting.Use the leaf tucking method and the box cutting your leaves.and to pull two er so leaves with that in SMALL moderations will be fine.but again I have to stress leaf tucking is really thee best method imo but yiu can easily do that just never over do it and its very easy to do with an auto.keep it small,simple and mellow n you'll be fine.do whatcha wanna do over the course of a week n a half er two.and Kelps in the soil will help stave off shock n stresses as well as CO2 during this stage especially if your gonna trim on her some.hope that helps ya man.be good dude."AFN smoke out"
