Are you sure that your humidity is at 70%. A digital humidity reader will give you a better and more accurate reading of the humidity.
Sounds like your snake is having a bad shed. After they turn cloudy they turn clear and look normal again. A few days later they should shed their skin in one big piece.
I would suggest maybe making a humid hide for her and giving her a soak. I prefer soaking my snakes in an inch of room temperature water with a washcloth in the tub with them so they have something to rub on.
