Cracking in slabs is normal and they saw lines in concrete to control the cracking so it occurs where the sawn lines are. A 1 mm crack isn't that bad.

That said for poured concrete, I have no experience with post tension cables. I kinda thought they are supposed to be pulled tight when you pour but maybe someone else knows. I'm sure there is a website on this.
