Your bloom nutrients usually have a minimal amount of nitrogen in them, all i can tell you is what i do and that is run small amounts of n during flower never any added just what is in my flora series mix and when i ran general organics it also had n in the bloom nutes just at lighter ratiosIm on at wk 4 of bloom stage and was wondering if i should cut back on nitrogen or maybe no nitrogen? Any help would be appreciated.............i did a couple searches on this but theres seems to be a difference of opinions.
