it looks okay..the 150hps wont have the light penetration that the 400 watter has, (the whole inverse square thing, how light diminishes more and more as its further from an object) so you wont get as much from it but i guess every lil bit helps. 5 ft away seems kinda far tho, maybe slowly move them closer over a few days to about 2 feet maybe...get a copy of cervantes medical grow bible, it will really help anyone out. good luck with it. and im checking out your grow journal lol.
