I say all you need is Grow, Bloom, Micro, Calimagic, and Diamond nectar (fulvic acid)
GH website has all the different feed regiments where they outline all the ratios per gallon. The light, medium and heavy feed charts are based on growth stage as far as i know.
I've used GH many times over the years and they are the grand father's of hydroponic nutrients.
And if you aren't sure and can't find your exact combo, then just go by the mix rates on the bottle.
