Your leafs are very important to keep your plant healthy.... if you don't know what your doing you can damage your plant and stunt it's growth very bad.... So you need further advice... if you want to start cutting leafs you should post a pic of your plant and tell others how old it is, post what you have done to it what kind of nutes your useing.... you will get back and forth answers about cutting leafs off... but I know you can cut some leafs off at certain times without damaging the plant.... but like I said don't just go hacking your plant up.... get some pics and you will get advice.
