Newbie Nutrient Help

G'day

I am 3 weeks into my dwc (originally aerogarden) grow using sensi grow a&b.
I am also using piranah.
There seems to be a lot of additional additives but i'm not sure which ones i should be adding. Any recommendations would be awesome.
I want to put a sprinkler in eventually so I was wondering if someone could recommend an equivalent nute which wont need so much flushing and have a lower salt build up.

Ok, so i've been looking around, and am also going to get/add Sensi Cal Grow & Bloom. Is this recommended.
I'm not able to get FoxFarm bigbud, but was wondering if anybody could tell me whether DR HORNBY LIQUID BIG BUD would do the same job. http://cgi.ebay.com.au/DR-HORNBY-LIQUID-BIG-BUD-1-LITRE-HYDROPONICS_W0QQitemZ310077976983QQcmdZViewItemQQptZAU_Seed_Starting_Hydroponics?_trksid=p3286.m20.l1116

I will probably use Flora Nova once i'm out of advanced nutes, since i want to add a drip system and from what i've read sensi leads to a lot of salt buildup.

Thanks again

i heard that about the sensi to, for veg i would say your fine using that stuff, if you switch to gh for flower i would recomend the 3 part, just because its whats familiar to me and get a jug of floranectar and liquid koolbloom, i used those on my last grow and it worked out good
