never used advanced nutrients. but i was recently shopping for nutes (1st time), and almost every other brand of nutes had customer reviews saying that "this kicks the shit out of advanced nutrients!" some examples are dutch master nutes & canna nutes. i'm sure advanced nutrients will do just fine though.

as for feeding schedule, it depends on the strain. some strains can take a higher ppm of nutes than others. i'd suggest finishing one plant of the strain you'll be working with in your SOG to get a feel for the ppm it likes (both in veg and flower). then, clone your ass off with those numbers. good luck
