Howdy Porcha, I have used (and with great results) the Armor Si, Diamond Nector, FloraNector, Floralicious Plus, and the Liquid KoolBloom with the base nutrients MaxiGro and MaxiBloom (dry powders). I have not used the liquid nutrient lines. The Maxi line comes in 2.2 lb. bags and it only takes 1.5 tsp/gal (at maximum feed rate) and does not need any 'micro' nutrient added. I use the local water which is hard enough that It does not require the use of CALiMAGic.
