Jumping spider fully grown?

[Witchwithoutabroom]

How do I know if my jumper is fully grown?
My female phidippus regius Florida is 1,5-2cm big, last molted in june.
I thought she was fully grown but hides away now for weeks (7th of September last meal)and won't eat. Her abdomen looks dark and huge, like it would in premolt.
She came out twice for a drink and that's it.

No insight but do jumping spiders stop growing or just slow down growing when fully grown?

They stop growing when fully grown, unlike tarantuals.

They stop growing when fully grown, unlike tarantuals.

Do they slow down their metabolism then and hide away for weeks after their last adult molt? Or do you think something is wrong with her? She's only 4 months old. It's my first jumping spider too.

Looks adult like, but I’m not well versed in Phidippus. Could be molting or laying an eggsack
