150w with qb-type spread... if it's only 8-10" awaay as in the pictures and 100% power, you might want to raise it a bit. 18-24" depending on size of coverage and how long you run the lights per day ... autos, so you get a lot more hours per day to provide what they need.
in the end you can use the internode length (the anatomy between gowth nodes) to determine between the two options given previously.
leaves should be propped up to some extent., but looks a bit more than normal, yeah. if droopy at end of day, it'd be a potential sign of too much light per 24 hours -- as far as eliminating possibilities or helping confirm others....
