Hardy,
don't get too down on yourself, even licensed doctors are still practicing, thats why they call themselves practicing physicians, cuz their still tryin to get it right after years of schooling. how long have you been growing.

take it as a learning experience, now you know some of the things to do differently next grow. from experience I know that the miracle grow is not enough to grow MJ and any hydro system is only a good as the nutes it uses

the halogen lamp isn't gonna do much either. if your budget is low go w/ a cfl grow they are cheap and you can get your feet WET (pun intended)

good luck and don't give up, your already here and there is a wealth of knowledge here at c-dot
