yes its not eating..

Just have patience Mist, I'm sure it will moult very soon and have a pretty new suit

Make sure not to try and feed it now, also remove any uneaten items.

Once your T has moulted, give it about 1 week to recover before attempting to introduce food.

still not eating and just keeps sitting on this web!!

Hey Mist,

If you look at the bald spot your tarantula have on the rump in the first picture and you look at the latest picture you'll she how dark it has gotten. This means your tarantula is in pre-moult.
Soon she'll have a new dress on.

@ hendrijs tyvm now for her friend,

this one has not eaten since September last year...??? gave her a cricket again today she runs away both off them 11cm

There is no given facts why some eat more and grow faster but only possibilities.
"Theraphosid spiders show considerable variation in growth rates both within species and within individual broods, the advantage of this being that some slower growing individuals from a brood may survive harsh conditions better than others by requiring less food, it also helps to avoid inbreeding by varying maturing times. As a rule males mature earlier than females, thereby reducing the likelihood of sibling pairings; these varying growth rates are both genetic and due to external parameters such as temperature and food availability."
