cns17 grow hydro in coco

  1. so my local shop is out of cns17 for coco but have the hydro formula and after looking at botanicare's website it appears hydro has 1% less calcium and 2% more K. can i substitute hydro for the coco formula and just bump up my calmag or do i really need the coco formula?
     
  2. you can use it, no problems
     
  3. shouldn't be any issues bro.
     
  4. I'd run RO filtered water with 5ml Cal-Mag+ to 15ml CNS17. Don't go over 20ml CNS17 during veg or you may wind up with cation issues due to the excess Potassium >200ppm. Should work out fine.
