How far away is each bulb from his basking branch?
I’d double check what you have in there with the veiled tested plants on the Chameleon Academy's plant list. Veiled are notorious for eating anything, so you want to make sure you’re only using plants that have been proven safe for veileds. Also make sure to put rocks too big for him to eat over the soil in the plant pots if you haven’t already. I’ve linked the Chameleon Academy’s plant list below!

@ToastyCham said, the ambient is too hot, he gave a good ambient range; your basking temp is too hot for your cham’s age, as well. It should be 80*F at the top of his back when he’s on his basking branch. How are you measuring his basking temp and ambient temps?
What specific brands and versions are you using? The schedule is perfect!
Stick to the gutload chart with the white background
@ToastyCham anttached above for gutload. Both the old one (first listed with green background) and Neptune the Chameleon’s list (based on your plants and other threads, I’m guessing that’s where you got your info) have kale in them, which is not good. Kale is high in oxalates, which binds calcium. More feeder variety is always better, so go wild trying the different bugs on the feeder chart above! Let us know if you need/want places to buy bugs from! Dubia roaches don’t always interest chams, so start with a small amount to test them out. Other easily accessible roaches that chams love (there are way more than this) are red runner/Turkistan roaches, discoid roaches, horseshoe crab roaches, orange-and-ivory headed roaches, and green banana roaches (these are the only ones that can climb and fly in what I listed, the others do neither)
If you could post a pic of the back of his back feet, we can check for tarsal spurs to double check he is in fact a he. Plus a regular pic of him so we can fawn over him of course! Where did you get him from?
That is too high for veileds during the daytime, you want it to be 30-50% during the day. What are both your nighttime temps and humidity levels?
Short spurts of misting at night are great, you can also make your night misting longer to help. Is your humidity gauge digital or analog? And did water get into it and break it?
Unless your nighttime temperatures are 65*F or lower, it is not safe to fog at night. Higher temps and high humidity increases the risk of a respiratory infection. If you can get that nighttime temp drop, make sure the fogger is cool mist, not warm mist. There are many options to choose from, you can search here on the forums for premade ones or even make your own!
@crosscutts has a great tutorial on making your own:
(the entire series is awesome!)
For his cage, I’d add some more branches and vines (that are safe) throughout, but especially near the top. If you want to do a full husbandry review, let us know! I’ve attached helpful links below (if you haven’t already seen them)!
