Ya man I'm in the same boat.
I planted my auto 2 days ago and it's super slow growth, can't even get it to pop out its shell.
Damn thing must be a bunk seed.
In all seriousness though, Autos are fairly slow growers when they start off.
Not to mention your plant is a week old? Most plants a week old don't even have the first set of true levels.
You gotta give time for the taproot to make its way down. Plants start off building the roots more than the top floor as they are born, and then start to grow faster once the taproot hits the bottom of the container.
That is when they start to spread outward and use up all the remaining space. That is when the growth takes off.
Also depending on your pot size, don't expect your Auto to be huge.
Contrary to what most believe, Autos can be big plants.
Take two of the same strain/breed, plant one in a 2L Soda pop bottle, another in a 2-3 Gal Smart pot and watch the difference in height and branching.
