@ChefGreenThumbGardenofWeedin, 3 quick answers :P
1. i stayed within the recommended amounts written on the bottle, increasing as i went.
2. its hard for me to say personally if it has made a difference because i didn't do a side by side comparison with and without it. that being said my plants smell AMAZING, and even after only handling the plant briefly, the fingertips of my gloves smell fruity, just amazing
3. i add it to the same reservoir as the rest of my nutes, adding it last. i found it lowered PH quite significantly. decent trick when i accidentally get a bit too happy with the PH UP.
