Need help with a sanke

[PowerVenus]

So I own a California kingsnake and there is something wrong with it :/ I got her (I don't know the gender but I assume it's a girl) about 2 months ago and she still haven't ate anything. I don't really know her age but just that she was hatched this years and she is kinda small ( I think even to small for her age) I guess she is probably 3-4 months old.

The other problem is that her feces are bright green and after some time it get's little bit more white. I didn't find any info about it in the internet but I assume it's not a normal color.

The habitat is suitable for her size, temperature is 32-28 C (UVB light is included) during the day and 28-26 during the night (heat pad is under one of the corners). Lights are off while at night. The only thing I do not know well is humidity, but I'm trying to keep it stable with enough water, spray water between 2-3 days. If the humidity is wrong for her I always leave a humidity box in the enclosure.
