@daniel.s See info below provided in bold color. Welcome to the forum.
Your Chameleon - i am 90% sure he is a male veiled chameleon i got him 4 weeks ago, at the pets store they told me he is 3 months old.
Handling - sinds i got him i handeld him poorty because he was very scared and hides, so lets say 1x a week.
Feeding - He is now eating house crickets and mealworms, i give him about 6-10 crickets (size 6) dusted with Sticky Tongue Farms calcium and 2 mealworms everyday.
Mealworms are not very nutritious. You can add other feeders like BSFL, different types of roaches and superworms. they should have a variety of feeders.
Supplements - Calcium Sticky Toungue Farms
Are you using miner all indoor or outdoor? He will need calcium WITHOUT D3 (miner all outdoor) on every feed except 2 times a month when you need to give him Calcium WITH D3 and 2 times a month he will need a multivitamin. Pick a day of the week and rotate between the two each week.
Watering - I spray his terrarium 2/3 times a day with a hand spray.
does he have a constant water source like a little dripper? These sit on the top of the cage and drip down the plant leaves on a slow drip.
History - I know the guy who sold the chameleon to the pets store and the pets store owners. I know he is a home breeder and not a huge like breeding farm thing.
Cage Info: Reptibreeze 40x40x100(cm) its a screen cage,
cage size is too small. You will need 61x61x122cm minimum for a male.
i have a Arcadia 23 watt day light lamp 7% UVB and a Arcadia basking light 100 watt (his basking spot is arround 30-32 °C, my lighting schedule is a bit of but i do my best to start at 9-10am and turn it off at 9-10pm.
Are you using Arcadia's screw in UVB bulb? LIke this one here https://www.arcadiareptile.com/lighting/d3-basking-lamp/
They actually do not recommend these for use on small cages. Only for much larger enclosures. They produce very high levels of UVB at close ranges. You will need a T5 HO fixture and arcadias 12% bulb.
You want to keep the basking level heat to about 29 degrees C. Once he is full grown about 12 months old they like it a little hotter but still no hotter then 32 degrees C. You can lift the fixture up off the screen a few inches to drop the heat level. get a heat gun to more accurately measure your levels.
Get a timer that you can set to turn the lights on and off at an exact time each day. You want 12 hours on 12 hours off in total darkness.
my temerature in my room is usually arround 20°C my humidity is arround 40-60% i live in the Netherlands so the temperature is pretty hard to keep it arround 20°C but the humidity is ~50% all the time.
Ok as far as temp as long as your ambient house temp does not drop below 10 degrees C. then you are good at night. No need to worry there. Humidity is also fine for daytime. You want them in a 30-50% max range for daytime. You can add a cool mist reptile fogger at night between the hours of 1-5am to boost nighttime humidity when the lights are off and the cage is at its coolest. Attach the tube of the unit to the top back corner or top side of the cage so it fogs into the enclosure.
my terrarium looks pretty boring but im going to fix that soon after i finish my exams.
i hope this is enough info
I think he is not eating due to the level of UVB be is getting blasted with. The lighting should be corrected asap. Here is some additional info that can help as well.
