Additionally I want to try something involving these two things....
I want you to order repashy supercal NoD

You will replace the EPA and the BIO dude with this. So that you are using NoD at every feeding and then LoD 2 times a month. The NoD is only plain calcium without D3. EPA has bee pollen and other stuff. then you are adding more bee pollen orally with the other one. You can use the bio dude in your gutload. Sometimes too much of a good thing can cause issues in their body. I just want to test this and see if it helps him.
Next I know you said you do not see him drink from the dripper. I want you to switch up your misting slightly. that morning misting prior to lights on. I want you to run this 15-30 minutes after lights come on. And then the one before lights off I want you to move that earlier in the afternoon say around 4pm. I want to see if he will drink if given the opportunity with a misting. Gout can be linked to dehydration and some chams just need the mistings during the day to get proper hydration. Some prefer the misting to a dripper as well.
