Welcome to the forum!
Please lose the fake plants and replace with live plants & vines
only. Live plants help increase and maintain humidity.
When you do replace with live, you'll need a plant light. For that size enclosure (36” x 18” x 36”?) this one is excellent:

Substrate is appropriate only for bioactive enclosures. If not fully bioactive, no substrate at all is better. Humidity is better achieved with live plants, and regular misting. The fogger should only be used at night after the appropriate temperature drop (for a Jackson's).
I would also remove the hammock. Beardies love hammocks; chams... not so much, and some hammocks can present a claw/nail hazard.
In lieu of manually pouring water on leaves, you may want to consider a dripper (can be DIY) or better yet, automated misting system (e.g. MistKing).
Can't see what you're measuring temp & humidity with. Analog/dial instruments are notoriously inaccurate. Digital hygrometers & thermometers with probes are more accurate, and better able to measure the various microclimates within the enclosure.
Placement: Chameleons feel most comfortable/secure when the basking site is at or above eye level.
