Your humidity is HIGH if you have condensation on the window.
Probably way higher than 64%
Next time purchase a humidity gauge and thermometer at Walmart.
Something cheap like this:
and calibrate them.
It is extremely easy to do and I will tell you how if you want to know.
You can NOT trust...
I know this sounds weird/dumb/wrong but trust me when I say you can not trust those numbers.
Next time you run the bator I highly suggest you purchasing seperate humidity gauge and thermometer and calibrating them both.
I would leave the water level alone for now.
