He all.....I could use some opinions here if you'd be so kind. I'm growing in an aero system(s) (20gal) 350gpm pump and 6 nozzles. I have 6 plants in each. I have plenty of HPS (1400w for 15sqft), and plenty of oxygenated h20 ((2) 12" airstones in each). I use GH 3 part and add hygrozyme with each nute change. I keep ph at 5.8 and change nutes once a week.
Here's my question: What could be going wrong such that I can't go above 700ppm in the 4th week of flowering without showing nute burn. I see so many people talking about 1200-1500ppm at this age.
