and Welcome To BYC! Hope your hatch goes well. Ya, if you can keep the humidity around 65% that seems to be what most recommend. If your humidity gets too high a lot of times it will "rain" in the incubator from the water condensing on the top and falling onto the eggs. With the eggs that had the wet spots, did you candle them to check if they were developing before you put them in lock down? One other thing I would worry about is if you have a leaking egg, one that is really rotten and the pressure is forcing the contents of the egg out of the shell, if they are bad enough to leak you can usually smell them, they can explode which will make a real mess of your incubator.
