Hey buddy I really hate to be the bearer of bad news ~ and take a deep breath before you read further :smoking::smoking::smoking::smoking::smoking:
You're dealing with a pretty advanced infestation of russet mites :(
Take a deep breath again (:smoking::smoking::smoking:), it happens to the best of us. You can scope a stem or leaf petiole if you want, but you can tell there there by the brown/golden dust that is right under the nugs on the stems. Those are all mites :puke2:
cut those plants down and clean your room as good as you can, and read up on here about russet mites theres lots of good info!
May the force be with you
