No offense but do you know the care needs for a GTP? Neonates are very particular. I would highly suggest reading up quick on care guides
First off your temps are way too high. Basking spot needs to be from above or the side and no hotter than 88 degrees but in realistic means, 84-86. Cool should be in the mid 70s. You need to make sure you have the proper tub setup with adequate perches to let them regulate.
Neonates can either be voracious feeders or very finicky. A finicky eater should never be sold to anyone until eating for a set period of time. 17 grams is far too small as they should not be sold before even close to 4 months of age and should be far larger than that.
GTPS stress very easily and take a while to get that stress response going. They can seem fine for a week or two then just stress out for a month.
I would make it as stress free as possible which means you do not handle or bother as much as possible. This means not misting directly on the snake and only opening the tub to change water and offer food.
How old and what locality is it? Where did you get it from and is it captive bred or wild caught/farm raised?
If it is feeding on live then you need to feed on live. I would also either get the complete chondro book and/or get on this facebook group and read up on this forum for how to care for neonates. If this is a wild caught or foreign farm import you need to get a fecal done soon to rule out parasites.

For now get that temperature under control, you have it way too hot.
Look here for perchs for tub setup that work great

Get in contact with the breeder for help. If you got it from a reptile expo, craigslist, or pet store that is not the breeder then I hope it works out.
Not trying to be mean but these are not snakes for first time keepers and should be researched for a long time before diving into.
