sorry dude i would help , but i wouldn't consider myself and expert on nute. but i do know that you dont wanna use soil nutes on hydro systems.
I also know you dont need nutes for the first weeks too.
here's what i'm using now with my Aerogarden"
general hydroponics- maxigro 10-5-14 (veg nutes)
general hydroponics- maxibloom 5- 15-14 (flower nutes)
i also think it is suppose to be good to drop your nitrogen level when choosing a flowering nute.
hope that helps
