Hi
Bit of a newb too, but my $.02: for aero/hydro, you want to keep your pH a bit lower. A little baking soda is a good way to do this cheaply. Also, there have been reports (see Teknique70's AG threads) of odd looking first leaves that fall off and are replaced by better leaves, so don't panic. Last, people feel strongly about fox farm nutes, and you can look up there grow tables. hope this helps!
