      Honestly, nutrients are so readily available in these kind of systems, less is more. I would just go RO and add in 100ppm cal and 50ppm mag (sorry I am unfamiliar with Shogun to know its cal-mag ratio). You probably wont need any base nutrients until another week or two to be honest, its the cal and mag requirement which will hit you - usually tap water is packed with it. Most cal-mag carries enough nitrogen until they start to get a big bigger - also running just cal mag will force roots to seek over nutrients and shoot into your buckets faster.

      @InTheSystem I have Shogun A & B and Shogun Cal/Mag. I have started to fill the system up with 100% RO. I was thinking stay below 400ppm tops.    I'll try it at 100ppm Cal/Mag first then up to 300ppm with the A & B see how I get on.    Just trying to get a rough idea of what folks are doing with the DWC and RO water, its still quite rare to see so info is limited.    I was flipping a coin over making up the first 100ppm with tap water to add any micro nutrients I may miss then fiddle with levels using the Cal/Mag and nutrients until I get to 300-400ppm.

      @FatBoy77 Is this true? I've just dug my 930 Agro lamp box out and it's exactly the same as yours, done a few grows with mine now and everything has been good besides my yields slightly down on my 400w hps. What problems are you having? you mention different colour specs? Mine was purchased a few years ago now so i reckon we are not the only ones here. Go dig out your boxes eveyone!   Here's my box. >
