I always got super organic flowers(add me to IG @colorado4weed2love0 if you wanna see pix of my crop and extractions), and if you add your nutrients to water you are doing hydroponics, you are skipping the food web and directly feeding the plant, you are not using your soil other than to hold the water and fertilizer you are applying, thats why you will get great results from hydroponic nutrients in pretty much any type of system which includes, coco, soilless , sand, gravel, rocks, etc, and i HIGHLY doubt you do a soil grow, that fox farm you use isn't soil. It's a soilless bagged premix, that's why it's base is peat moss (a soilless medium). Nearly all indoor grow mediums are soil less including coco-coir, peat moss, gravel , rocks, etc...
Ingredients:
Composted forest humus,
sphagnum peat moss, Pacific Northwest sea-going
fish emulsion,
crab meal,
shrimpmeal,
earthworm castings, sandy
loam,
perlite,
bat guano, granite dust, Norwegian
kelp, and
oyster shell (for pH adjustment).

So just so you understand what your grow style is , it's considered soil less hydroponics drain to waste. I've read where you posted to water to run off as well, that's another sign of drain to waste. Those salts you are adding killed all your soils microbial life and now you just use it to hold your salts and water, you would see better results using this in a DWC/RDWC system, i stopped growing soilless DTW hydro(i used coco-coir, but started with peat mixes such as FFOF and happy frog) and moved to RDWC and saw huge increase in yield before i went fully organic, and once in a while i bust out my RDWC system for stupid high yields.
