shedding/humidity

how humid does everyone keep there cages during shed. he's about to shed i have it real humid but i dont want him to get scale rot or anything. if someone has any advice...

Usually between 60% and 70% is recommended, and 50-60% during the norm.

it gets beween 60 - 70 all day, but condensation builds up on the tub if its too humid what are the signs of scale rot? i dont want to mess with him because hes in the shedding process. or is a few days of too much humidity even enough to get scale rot
