Thanks for all the info.
The plant really seems to like its current potting mix combination. So I am hesitant to disturb the roots again and change the potting mix again.
For now I will move it indoors near an east facing window and set it on top of a humidity pot. This location still gets around 3000fc from 9AM-11AM and then tapers off to 1000-2000fc the rest of the day as the sun is on the other side of the house in the afternoon.
I do not like to introduce too many changes to a plant all at once. Doing so introduces too many variables that are hard to pinpoint and control.
Moving it to its new location allows me to reduce the light and temperature. I hope that this will also reduce the plant's transpiration and evaporation so I can stick to the usual watering every 2-3 days.
