Remove the humidifier that is directly going in his cage, great idea but It causes URI, unless your cleaning it everyday there’s bacteria that grows inside the tube. Just Keep the humidifier near his cage. the only time a chameleon needs high humidity is at night and early mornings. In my research over time and experience, there should be little humidity once your basking comes on. I did not see if anyone said anything about that. I can forward you a link to a great herpatalogists that spent his life studying chameleons. Again i spray before basking light turns on and at night after I turn it off. I own 7 panther chameleons and one veiled.
