On the shell, is it mostly softer towards his tail? It's normal for a little turtle's shell to be somewhat flexible, especially towards his tail. It should gradually harden until by a year, it should be all hard. At 3", I suppose your turtle's shell could still be somewhat flexible towards the back.
The calcium blocks that you buy aren't that good. Instead, put pieces of cuttlebone in the tank for your turtle to snack on. You get cuttlebones in the bird section of the pet store. Turtles eat them. They are quite inexpensive and very good for the turtles.
The cuttlebone (along with other food) will provide calcium but your turtle won't be able to absorb it unless he gets enough UVB light. That's why it's so important for turtles to have good UVB basking lights. The UVB causes his body to manufacture vitamin D, which in turn enables the turtle to utilize the calcium in his diet. Calcium, of course, is the chief component of his shell and bones so it's vital that he get plenty of it.
