Yea definitely don't use too much sulfur it tends to burn the plant, i use my amendments when i make my soil. It cooks for a few months in my garage to get the microbes going and cool it down.
And you likely need all of the stuff you put in. But saying an additive makes more terps. Or more trichs. Or even more plant. Is just not how it works.
Now the light spectrum and uv stuff. Science and results are showing something there.
But a complete nutrient profile for an individual plant type is all that is needed. We will know the proper NPK and micros soon enough from legal weed. Just like the corn farmers know exactly what their corn needs. The differences in flavor and such is from breeding. Not feeding.
And the farmers will say that the "sugar water" or something is their secret just like us. But they are mistaken as well.
It's not so much that some soils are better for plants. Just that some are lacking what they need. And when we add the missing ingredient and the magic happens. We come here and post what we saw. Like we did something special.
I guess that's what Bro science is. I never heard the term until I came here.
