Is the minerall with or without D3? (indoor/outdoor?)
An appropriate schedule would be calcium without D3 or Phosphorous on most/all daily feeders.
Calcium with D3(no Phos.) twice a month.
A multivitamin twice a month.
(the last two can just be alternated every sunday)
Repashy Calcium plus is an all in one, and can make this much simpler.
I understand the products you are using to be quality products(ive never used them) you are just misusing them.
When my jackson was being ODed on D3, she started crawling the screen, and would slide off of it. She would fall 4' 5-10+ times a day, and was super hyper. D3 8 times a month could cause this, if the minerall is indoor, that means you are giving D3 16 times a month, and thats if your only dusting one feeder a day.
The chameleon in the picture looks dehydrated. While it may have early onset of MBD, I see no obvious physical signs of her having it. (curved/deformed limbs)
So if she has it, it is early, this is a good thing.
Im not sure what Vit-all is, but I know those orange cubes are not the way to go. Here is sandrachameleons blog on gutloading:

By the sound of that poo, you need to get a fecal done, I understand green poo is a sign of parasites.
A 75watt household bulb gives me a basking of 90-95F.
This is what you need to achieve, one way or another.
It is my understanding that females should ideally be kept cooler though, 85-90F, to prevent egg formation. Preventing egg formation extends their life span.
Your in Houston, so I imagine your RH is fine
I would stop ALL supplementation immediately, and get her in a shower chamber once or twice a day until she doesnt seem dehydrated, if she is. Post some better pics when you get a chance though.
After a week, I would start with just calcium on feeders.
After a month, start her on a normal supp schedule.
This will give her body time to balance back out.
EDIT: How long have you had her?
ANOTHER EDIT: I have a strong feeling your chameleon has a parasite problem.
