noob with nute questions

Ok so I'm about to start my first grow. I've got a 600w mh/hps with a home made 10 plant hydroponic bin. I'm going to start with snowryder, blueberry and bubblelicious, all autoflowering. I've been doing a lot of reading but still haven't been able to come up with a clear answer. I'm trying to figure out exactly what nutrients and additives to use for my plants and what NPK values I should be looking for. To try and get an idea I went to a hydro store but they have a whole damn wall of nutes with all different concentrations and parts.

So basically I'm wondering if someone with autoflowering grow experience could tell me the exactly products they have had success with.

Updates once I get my seeds on my first grow

theres companies that make specific grow and bloom formulas. pretty nice for noobs and lazies.

Really how much do you wanna spend on nutrients?
I use nothing but advanced nutrients and with my budget I went back to the generic Micro, Veg, Bloom nutes and there is nothing wrong with using it so far.
I would say since your just starting out, do that. Get something easy to understand and mix....til you can start to standup on your own and figure out whats best for you

Well I'm not looking to spend hundreds of dollars but I plan on growing more after this first one. So just a 2 part advanced nutrients system with no additives or should I add some big bud?
