Some people mist their plants everyday, and foliar feed them once a week. I am not one of these people. Maybe I should try it someday. I misted my plants everyday for my first two crops. To much of a pain in the ass, I thought. You have to mist them when the lights are off, and yaddy, yaddy. I have my system set up to be as Auto as possible. I did think about building a fog system, that would turn on once a day while they were sleeping, but never got around to it. I do know you can over Mist plants though, especially if you water a lot.
