I was just wondering how high my new SF7000 should be above canopy during flower? Manufacturer recommends 18", others have recommended 30-36. Also, Humboldt's Bloom booster. How often to use during flower and is it necessary to switch to something with higher potassium and less phosphorous? Is it worthwhile at all? Should I be using a hardener? FYI i'm in ocean forest, water/feed every 3 days, using full foxfarms and humboldt's line-up. I've seen zero burn despite feeding recklessly and may have stunted 2/6 but they're doing better. Using distilled and water only every few feedings. 5x5 space. Currently maxed out on light height at around 29 inches from canopy. 5 autos/one background photo.
