Using 18/6 on mine. Nutrients for my hydro - turned out okay with 300ppm for first few weeks🤷 after they grew up some I went to 450 then 600ppm during flower. Around 700ppm right now but they haven't shown any signs of wrong doing. Maybe more could help but these numbers have worked so far for my first grow..... Btw I gave no nutrients to the rockwool I let the roots stretch down in to my resovour which was 300ppm
