Bro are u asking how u should use ur nutes? Or asking what brand to get lol?
IF this is ur first grow then ur gonna want to start off with "VEG" or grow nutes.. Once u have an established plant that has succesfully matured thru early stages of the GROW phase then ur going to want to switch ur lights to 12/12 and go to Flower or "BLOOM" nutes man..
THis will help ur plants mature and sex and tell u if they are going to grow flower or grow bud that u can smoke or if they are gonna grow flower's to pollinate ur BUD..
LOL im smoked out and didnt quite get ur original question.
