Nutrient Question

I am using the General Hydroponics line of nutes plus CaliMagic & Hydroguard with good results so far (at mid-flower).
My question is can/should I use a microbe additive? I have a bottle of "Photosynthesis Plus" left over from the FF days. No big deal...just want to ask before disposing of it
Here is the product description:
<<<>>>
Photosynthesis Plus by MICROBE Life Hydroponics is a breakthrough in biology and biophysics once thought impossible to achieve. By driving and accelerating the processes that contribute to overall plant vigor, Photosynthesis Plus will accelerate your time to market while improving your plant growth, vigor and yield.
Photosynthesis Plus is a novel culture consortium that contains stable microorganisms capable of improving plant conversion of carbon dioxide to available carbon to fuel plant requirements, and drives plant biology at both the foliar level and the root zone.
Photosynthesis Plus rapidly establishes essential plant-supporting biology, even in a media void of organisms. Combined with its ability to improve the plants’ own photosynthetic machinery and inhabit the root zone, Photosynthesis Plus will help to accelerate and optimize plant functions.

Thank you

is it OK to use in hydro? if so, sounds OK to me. just prepare to dump your res if it gunks it up.

and to save you $, use southern ag garden friendly fungicide instead of hydroguard. million times more concentrated

Its good in hydro just didn't want to over do it.
Gunked up reservoir? Been there done that!
