Chameleon sleeping too early?

[SuperFastSlug]

Hello everyone. My veiled chameleon, Oscar, seems to have a problem: he's falling asleep really early. He used to sleep just when the lights went off, and now he's usually falling asleep at around 4. Today, I caught him falling asleep at 3pm! He seems to be healthy otherwise, though. He's very active when he is up, eats great, normal bowel movements, and still hates everyone. Here's my setup for him:
Enclosure: 2' by 2' by 4' screen enclosure
Plants: Ficus tree, pothos plant
Lighting: 100w Powersun 26w Solar glo
Feeding/Supplementation: Fed about 7-10 feeders every other day. Either crickets, superworms, or roaches. Repcal Calcium w/out d3 every feeding, Reptivite w/d3 twice a month.
Misting: Heavily misted in the morning, set up to mistking which mists lightly 4 times a day. also has a dripper at the top of the cage. The cage is allowed to dry completely after each misting.
Cleaning: cleaned every 2-3 days.
Can anyone help me out please? Thanks! Any help is appreciated!

It is not unusual for them to settle in a few hours before lights out. What time do your lights normally turn off? Also sometimes if it is a cloudy dreary day my boys will go to their sleeping spots before the lights go out. I would just keep a close eye on him. If everything else is ok like you said (eating etc.) I would not worry too much.

My lights typically turn off at 5:30. And yeah, everything else seems to be normal. Thanks for the help!
