I’ll be putting my feedback in red. 
• Willow is a veiled chameleon, I'm pretty sure she's a female and I'm unsure of the age, maybe 3-5 months
Love the name! She does look like a pretty little she to me.
• I have never handled her, I got her three weeks ago and she's still shy around me.
• I feed her two super worms at around 7 am when she wakes up and about two crickets at 1 pm and three mealworms around 4:30 pm
Attaching feeder and ‘gutloading’ graphics. It’s best to feed just once in the morning which gives time for basking to digest. The feeder graphic will explain about feeder choices. I’m not the best at determining age, and feeding amounts vary by age. I’m going to guess she should be having around 7-8 feeders once daily. As she starts reaching about 6 months, you’ll want to cut her back to feeding every other day. We try not to over feed our ladies as they reach maturity to help reduce their egg laying and I’ll make a separate reply addressing that.
It is important to feed the feeders well so that they provide more nutrition. I feed my bugs fresh dandelion greens, watercress, chard, collards, various types of squash, sweet potato and Repashy Bug Burger in which I’ve added some bee pollen. I keep them well fed so I don’t need to specifically gutload.
•I don't really have a supplement schedule yet, I've given her worms dusted with a multivitamin twice
Proper supplements are essential! A great schedule is to lightly dust all feeders at every feeding with a phosphorus free calcium without vitamin D3. One feeding every other week you’ll use Reptivite with D3. The Reptivite is a combined multivitamin and D3 and is a good and easy choice.
• I hand mist her cage about three times a day when I notice it's getting dry.
You do want the enclosure to dry out in between misting. Usually misting 2-3 times a day for at least 2 minutes is perfect.
• She's pretty consistent, her feces is a dark brown, almost black with off white urinates.
• I just got her April 1st, I don't know much about her.
•She has a 24x24x48 inch reptibreeze mesh cage.
Beautiful!
•She has a 75 watt white heat bulb and a 24" reptisun T5 HO UBV light. I turn both lights on at 6:40 am and both off at 7:00 pm
Great! What strength is the uvb bulb? If 5.0 or 6% you’ll be perfect and want to make sure basking area is about 8” away from lights. If anything higher, you’ll need to make sure that there is about 12” from the light to basking area.
•I don't have a temperature gun but her overall cage temp stays around 70 degrees day and night, I measure by a temperature and humidity level combo.
This is most likely the reason that she is dark. Basking temp should be around 80f. A digital thermometer with a probe is the best way to measure temps. At night lower temps are ideal.
•Humidity levels stay around 40-60 in the day and they stay around 30-40 at night.
So daytime should be between 30-50% and at night can/should be 80-100%. Many use a cool mist humidifier at night to boost humidity. I love my Mist King and instead set 2-3 brief misting during the night to boost humidity. I think I need an automatic misting system, which do you recommend for good affordable options?
Mist King! While you can find Reptirain and such a bit cheaper, they can’t come close to Mist King for reliability and flexibility. They are well worth the extra cost.
•I have four types of plants in the cage, all live. I have a golden pothos, a cordyline, croton plant, and I do forget the name of the last one but I know it is mostly safe as long as she doesn't eat it.
I can’t find much info if the cordyline is safe for reptiles. As veileds do eat their plants, they do need to be safe.
• The cage is in the corner of my dining room, people mostly pass by but don't stay in the room often. The top of the cage is 70 inches from ground.

• I live in Ohio (United States), the weather ranges in humidity and temperature so it is hard to say
