Calcium Deficent?

[Yellow Turtle01]

Is there a way to tell if a turtle is calcium deficient? I'm inquiring because recently I've noticed my female RES's nails seem to be a little 'worn down', and she doesn't really have hard rocks to climb up, right now while they are waiting to move into the stock tank, she's in a little kiddie pool.
She always has a cuttlebone piece, which is usually there for a month and then gone but I know she's getting calcium. She sheds great, she recently she finished another big shed, and her beak looks fine, so is it just a 'nail thing'?
EDIT-She had to be upside down because (fortunately) she really dislikes being picked up, and 'normal way' she was trying to air swim, and I couldn't get a shot
What's it look like to you?

Those just look like worn down nails....if she is in a pool, she is likely brushing her feet/nails against the pool bottom alot....so would make perfect sense for the beautifully trimmed down nails...

So her digits aren't too short, then?
Okay, that's great, I was worrying she needed to grow them out!

I don't think that they are too short....if you notice them "nubbing" up close to the flesh of the foot---then that would be bad....I would just keep an eye on the turtle whilst she is waiting to move into her new digs....
