I added up all tje numbers on my technaflora nutes, 8-14-19 and I run at 2/3- 3/4 strength.  As far as limit, I can say at full strength plants don’t really like it. I belive the nute company put out higher recommendations than are required to make more money. I’m sure there’s some strains who wouldn’t mind full strength but none I’ve found so far
