I havent noticed a decline in quality going from organic/soil to hydro. I agree that the taste is a little better, maybe, its hard to tell, i think it has more to do with curing it properly. I also have come to believe less is more when it comes to fertilizer, trying to force the plant to uptake more than it can handle will just burn it and hurt your end result, im sure you guys know this, i learned the stupid way. Once i have a house and room for it, i really want to test different methods. I have done some testing to see what works, however. You cant go overboard, you have to read the plant. I will say theres some noots that make the plant taste bad. Im not sure what people use, maybe ammonium nitrate, but theres commerce around here that tastes like rotten cigarette butts and sparks when you burn it. Anyway, dont be worried to try new things, ive been getting 30%+ yeild with hydro, and no sacrifice to quality
