1. Definitely add more gutloa ingredients, more is better! For a scale, using a kitchen grams scale or a reptile-specific grams scale each work! Here’s a quick search with great info on how to set one up good:

2. Perfect!
3. When you take him to the vet, bring a fresh fecal sample with you (duh) and do bloodwork (he’s old enough to do it safely) and x-rays as well, just in case. Also make sure to drop off at least 2 more fresh fecal samples afterwards to make sure no parasites were missed.
4. His cage needs lots more foliage, as already said. Again, plant lights will help, as well (Sansi lights, Arcadia Jungle Dawns, and plain T5 HO 6500K bulbs all work great!). Try to use mostly live plants if possible (the two plant charts that were posted are great references, along with the plants module on The Chameleon Academy)- you’ll have to see how much the humidity changes with them, along with more vines (preferably live only, but if you have to use fake, only use the minimum possible and use a brand like Fluker’s, make sure it isn’t moss or Exo Terra vines!). Do you have a proper drainage system installed underneath the cage, and do you have any substrate in the bottom of you cage? Sorry, I have to ask, the pic doesn’t show it! (PS- What I meant to say was a full pic showing the cage when facing the front/a side of the cage, that showed all the way from the lights down to the bottom of the cage in in the pic, not a pic down the cage from the top! Sorry, I can see how that can be confusing!) Here are two great cage set-up links:

5. Does his T5 fixture have an plastic covering the bulb? Do you have a Solarmeter 6.5? Definitely get one if you don’t have it already, and if can afford it, it’s literally life-saving! It’ll tell you where to properly place his basking branch away from his UVB bulb, tell you when to actually replace his UVB bulbs (when the readings are cut in half!), plus tons more! If you don’t currently have one, his basking branch needs to be 8-9” below his UVB bulb for a safe UVI level of 3. How far away is his heat bulb from the closest branch?
6. Could you get his night temps any lower than that, like closer to 65*F?
7. Okay, you need to stop that humidifier ASAP! If you want to fog, you can only use a COOL-mist fogger or humidifier at NIGHT ONLY, and only if it’s lower than 68*F! Daytime fogging and warm-mist foggers/humidifiers can cause respiratory infections!
