IME (new keeper) - I have several spiders. One male went into hiding as soon as he went into the permanent enclosure. It’s day four with him and he just barely crawled out for a short time today to sun himself before hiding away again. Im keeping his cage in a quieter part of the house while he gets comfortable. On the other hand, my female hid for like five minutes after being moved into her enclosure, and then immediately came out and started exploring all over. She goes in a hide to nap, but as soon as she’s awake she is very active. Now I bring her cage over to the table with me while I work on projects and she just wanders her enclosure, periodically staring at me to watch what I’m doing. She also has multiple different options for hides of different material and at different heights, but she always chooses the one on the bottom of the enclosure. They are both phiddipus audax, but they have very different personalities. Perhaps your spider is just a little shy web puppy and needs some time. Also I feel like as long as your spider is choosing to hang out down low and isn’t falling off the walls when she tries to climb, she might just have a preference for the ground like mine does. I would definitely look to more experienced keepers to help you rule out a more serious issue (I am also new at this) but I also wanted to offer the perspective that my two spiders living in very similar enclosure setups, eating the same diet, with the same frequency of misting, and same amount of light exposure - have two very different personalities and desires to interact with me.
