My babies are stretching!

Germinated 5 Supergirl seeds last Saturday. Placed them in soil Monday and then they went under the light as soon as I saw sprouts. They looked fine last night but checked them this morning and saw a good 2-3 inches of stem between the soil and first set of leaves forming. They are under a 400W HPS and the light is about 2.5ft over them.

Any reason for this? I've had the exact same setup before and they did not stretch like this.

I didn't fill my cups up to the rim but I just now filled to the top with some soil. Maybe it has something to do with the strain?
