I use 1micro, 3grow ,1 bloom per 2 gal in veg, then switch to 1-1-3 per 2 gal for the first week of flower then 1-1-3 per gal for the rest of flower, until the last week i run straight water(for ebb and flow).Also u want to add the micro to the resevior while u r filling it, then when its full add the grow and the bloom, because the micro will lock out nuts in the grow and the bloom if not diluted. Luck to ya
