First timer, so feel free not to listen to me, but I've been dealing with the same thing. No humidifier though, so I just turned my fans down and pointed them a bit less on my buds. Also they are hanging in my bathroom (darkest room in the house that has space) so the humidity level is refreshed by the [occasional, lol] shower, I put the super dry nugs in a jar to cure as a test even though it's only been 3 days. There's a heat spike/record in my area of California right now, 100 outside and the humidity is 13% today!! So don't worry if they're drying out too fast, nature is just doing its thang. Unless the buds are dry enough that they're crumbling off to the touch I wouldn't worry too much, the outer layer should be a bit crispy. You can always up the humidity level and watch out for mold but if they're drying at their own pace common sense says to follow that pace, not to resist it.
