I luv it, my advice is premix it with a gallon of water or that shit will sink to the bottom of your Rez. This is what I am running in my 40 gal Rez. 240ml micro, 480ml bloom, 240ml Koolbloom liquid,80ml protekt, 80ml cal mag+, 40ml floralicious + and ph down. Gives me a TDS reading of 930, or EC of 1.9 the plants seem to be loving it! For as bad as it smells, it makes your weed smell and taste so good!
