Really? They stretched much yet? What sort of lights-off temperatures you getting? Nothing between the branches and where they join the stem?
By week two they should have a sort of "flowering shape" to them, that is the plant changes shape from when its in veg (sorta starts to "clump up" at the top)...how long are they from seed actually? They might just be too young to flower yet...
And if you wanna get a REALLY nice smell now, rub the stem gently under your thumb, then sniff your thumb...its beautiful!
Week 6 of Flower:
