BP hunger strike question

I purchased a BP girl back in mid june from someone online who claimed her to be feeding aggressivly off tongs. Yeah right. She's about 600 grams and has not taken a single meal for me. I've tried offering her both live, pre-killed, and frozen/thawed. I've tried mice, rats and she just refused ASF today (which I thought would be the winner.) I've offered appropriately sized rats down to rat pups left in over night. I've tried feeding in her tub and in a seperate feeding tub. I've tried different times of day and at night. I've lined the bottom of the feeding tub with newspaper, tried giving her a hide to hunt from, tried different substrates other than newspaper. She's gotten freshly dead to extremely rank f/t. Ive left a small tank of live rats in the snake room for a few days hoping the constant smell of food would make her interested in food. It made everyone else pretty hungry and launch out of their tubs, everyone but her.

I got her clutch mate at the same time who was also refusing meals but once I offered a mouse she took it instantly and has taken mice every time offered. While not my preference, at least she's eating now. My initial thought was both were on mice, not f/t rats as the seller claimed but since the smaller of the 2 isn't eating at all... I'm starting to think he sold her because she was a problem feeder because the last several entries on her feed card she refused for the seller. (Whom I've not had any luck getting help from, all he had to say was "oh she ate just fine for me sounds like a problem on your end")

She's currently in a 32qt tub in my vision rack, newspaper substrate, hot end 88 cool end 75-80 and she does have a small hide in her tub (she was extremely nippy when I got her and very stressed, she's calmed down since I gave her a hide and doesn't seem to get stressed when I handle her) and I did leave her alone for about a month after I got her to let her acclimate to new surroundings. I don't think it's necessarily a husbandry issue. All my other snakes are in same environment and feed just fine. And she no longer tries to kill me when I open her tub or stays stiff as a board when I am holding her... I think this is due to the hide since she stopped being a brat within a week of getting it.

Her feed card from previous owner is as follows (from april on)
4/1 FZ
4/5 FZ
4/9 FZ
4/14 new cage
4/16 FZ
4/20 609g
4/23 FZ refused
4/25 FZ refused
5/1 FZ refused
5/1 new cage 32qt
5/2 FZ refused
5/7 FZ
5/13 FZ
5/17 blue
5/21 shed 612g
5/22 FZ refused
5/29 594g empty
6/4 FZ
6/8 FZ refused

I'm assuming the FZ off his feed card refers to f/t prey.
I got her on 6/13 and offer her food every friday and she's refused since. The day I got her she weighed 630g and is currently 597g.

So... does anyone have any thoughts or suggestions? Should I just leave her be for a while longer since her hunger strike hasn't really been all that long yet or keep trying? I offer every friday with varying techniques no luck. Live food is only left in with her for up to an hour and is checked on frequently to make sure it's not trying to eat her (she ignores it) f/t & prekilled food has been left in as long as overnight and she's ignored that too. She frustrates the crap out of me because she's supposed to be my prized ball python and instead shes the biggest pain in the butt.

My normal just ate after about 2 1/2 months of fasting, he currently weighs 925 grams. My only suggestion is that is long as your husbandry is correct offer the appropriate sized prey regularly, for me it was every 10 days. As long as your ball is not losing much weight, it should eat once it's ready.

I got a girl in November and she was about 1200 grams and she just ate for the first time for me about a week ago. At about the same time in November my pastel female stopped eating she was almost 800 g. She just started eating about a month ago.

I just kept offering about every other week when they refused. I will say that they never did strike that I saw their first time after their strike. I would try to feed at 10 or 11pm and when they didn't strike I would let it sit over top of the heat tape. I would check in the morning before work and it wasn't there.

As long as its not loosing too much weight there is no reason to worry.

Figured as much. Now my next question, what's considered too much weight lost or underweight for her age/size? I haven't had much experience with them going off feed and when my bigger females did it didn't bother me because I knew they could afford to not eat but 600 grams just seems small to me to be losing weight. I'm so used to all my other snakes who eat good and gain weight steadily, never really had one this small actually lose weight. Closest I've come is just have a few slow growers who put on weight more slowly.
