Im with Tip top,,, I decided on Humboldt nutes (not humboldt county!), and I had better add the " extra sauce" because the part a&b are incomplete nutes for complete growing, its designed that way, unlike Gh floranova,,, sufficient for a complete grow... So, as I agree most nutes are complete, but a few, adding all the extras are a must.... otherwise you will have deficiencies.. Al, I read you like the h202, but I ran across brown algae, even at higher rates than you recommended, the h202 just fed them so they grew more, additional h202 in the amount to kill off the algae would more than likely killed off the plant also, I switched to bennies and a nute that uses amino acids and my plants love it.... There is a thread on here started by heisenburg about beneficial bacteria and the benefits your plant will have, just use nutes that dont have high salts, they will kill the bennies... Im a believer ....
