alot of people will tell you not to cut leaves but i do it and have had no problems.i don't do it alot but sometimes they just have to go.just don't do many at once or you could stress it pretty bad

and your plants look really good why do you want to trim leaves?only do it if they are blocking light from a budsite and you can't tuck them.i am pretty new to indoor but i have had no pros thus far
