There’s zero need to apologize for posting and asking questions. I’m going to ask some questions in return.

Are those measurements from inside her enclosure? What has her basking temp been?
Live plants will boost and maintain some humidity. To further maintain it, you can grab a dollar store shower curtain and wrap the back and one or both of the sides with it. Just be careful if you use tape to make absolutely sure there is no way for her to have any contact at all with it. I use very fine wire to attach things. Only run the humidifier at night when temps throughout her enclosure are at least 68. You want a good temp drop at night and they can handle temps in the 60’s pretty easily. Running it during the day, combined with the heat of her basking area increases risk of respiratory infection. If even with her light, her basking temps are well below the desired 80, try a stronger wattage of bulb. Just keep a close eye on it when conditions change that it doesn’t become too hot.
Btw, what is wrong with your humidifier? If it works, it’s fine.
