Yes it's a t8, he's about 10-12 in from it and from basking about 8 in, I'm using a 100w zoo med basking bulb, I take the temps with a temperature gun and no it's not on top of the screen
If it's a T8 tube , even if it's rated at 10% UVB , if he is not able to get closer than 6" from , assuming there is not a screen underneath the UVB tube and fixture, he'll never get enough UVA and UVB.
The results of insufficient UVA are lethargy and lack of appetite.
The results of insufficient UVB are insufficient metabolisation of dietary calcium, insufficient blood VitD , and this can after a short while result in stunted growth, and poor development and MVB.
If the temperatures are too low , he will also be malnourished because reptiles require heat to digest their food.
I recommend you move the T8 closer to where he basks ( a lot closer and double check it's rated AT LEAST 10% UVB , if not the T8 must be replaced with a more intense tube which produces very high levels of UVA and UVB ..... this is CRUCIAL.
I also recommend you double check your temperature, basking spot at 100 degF.
If the basking light is a colored one - throw it away and replace it with a clear colorless par38 incandescent globe and adjust the basking position height by trial and error until you are getting 100 degF - 105 degF at the basking spot.
Make sure your photoperiod is long ( I recommend at least 14hr , I run my lights on for 16hr per day and my lizards are thriving).
You need to offer AT LEAST TWO live insect meal to the hatchling per day, as many high quality live insects as it'll eat per session (BUT only 2 or 3 insects at a time so you do not overwhelm him with fast moving bug hopping and scurrying in all directions.
Change in poo habits / quality is dietary I suspect, he's actually malnourished and NOT eating enough insect protein.
