yeah something is obviously wrong. 400watt HPS and 41 days should give you 1-2 foot plants. How far is the light away from the canopy? Have they been topped? Is there any reason they would be shocked? And yes, what size pots? That would be my first guess without knowing any details (provide more details, get a better response), is that they need to be transplanted.
