Make sure the light is within 6-8 inches of her to reduce stretching, but yet still far away enough to not burn her.

Autoflowers do not like transplanting, you should have started her in a pot that can sustain her entire life cycle.

As for the stage she is at, for the 2nd week that is a little on the slow side but I'm putting my money on the window sill light she received for the first 2 weeks of her life.

I my self have never done auto flowers so they intrigued me to do them this season, I have 4 getting ready to hit the green house next week. They are only on day 2 of sprouting from soil and have already seen the first real set coming through. Keep her under that LED and add a few more if you can and I have no doubt she will turn out great.

Mind you, auto flowers only end up about a foot to foot and a half when finished in most cases.

GL man.
