Good organic nute for AUTO Strains? Plz help!

Sup yall, I am gonna be starting a 400 watt AUTOFlower grow but dont know which nutes to use..? Is fox farm fine? I dont want something crazy expensive but can spend some change if its worth it. I know you dont need growing nutes as they only veg for 3 weeks or so so theres enough ins oil to keep em happy. But whats a good organic flowering nute?

Thx

What stain are you growing?
I'm growing diesel ryder and i bought http://www.amazon.com/Fox-Farm-Soil-Nutrient-Trio/dp/B000HY2IXQ
Even tho they only veg for 3 weeks its still nice to give them a little bit of veg nutes before they go into flowering.

I'll be growing Low Life's Auto AK-47 and Blueberry aswell as Kannabia's Auto BCN Diesel and a Sweet Dwarf from serious seeds. I used Fox farm for my previous grows and it worked fine..but am really wanting to put some weight out on this grow so dunno if something better isout there.

In my opinion you can't go wrong with the Fox Farm trio pack (Big Bloom, Grow Big, and Tiger Bloom)

you could try bushmaster and gravity from Humboldt but if u want a monster auto your going to have to go hydro
