I agree with Deb, no such thing as too humid. Imo, you're panicking for nothing. It is very hard to see them by candling, especially early on because it is mostly fluid all the way to the end of incubation so the only way you could see them is if they get right in the perfect spot up against the side of the egg to give you a shadow. Don't worry about that. Just leave them alone and maybe just peak at day 56, do not cut until one pips on it's own, since this is your first time with this setup, you have no idea when they will be ready. Just be patient, at this point you can't save them if they are bad but if they are still good you can definitely kill them by messing around with them so just leave them be until they start pipping. Good luck.
