I've used it for a few runs now, and i dont think you can really over do it. i have used up to 15ml per gallon in flush which is 2x the recommended dosage. great results.
I've used this stuff for a few months now and has become part of my regular recipe.
It increases terpene profiles for sure, my buds reek and its been proven in lab tests.
i strongly believe the stability of the genetic is very important... some breeders are breeding under HPS lights which is far from natural sunlight and mutates the genes... over generations this type of flaws start to show in forms of herm plants or other mutations... just my $.02
