I have the same nutes, though I am switching to all Fox Farm, I was told to use FloraGrow for veg and FloraBloom for flowering, and use FloraMicro through both cycles, veg and flowering.
Make sure, too, that you are mixing your FloraMicro first in the water before mixing either of the others, and never mix the chemicals first before adding water.
ie: If you have a gallon jug, then mix FloraMicro in there with the water, according to label, and then after shaking and mixing thoroughly, then mix either your FloraGrow or FloraBloom, depending on which cycle your on.
