Hi guys I need some advice im currently using 20ml part a 20ml part b, coco nutes per L, 20ml cannaboost, 6ml pk 13-14 and my water isn't above 400, runoff is around the same, how can I up this even more?
First, calibrate your instrument to prevent mistakes.
Second add more nutrient for sta stage you are currently running. If the ec does not rise up change nutrient they are expired for heat exposure maybe. But it’s a strage problem it can be that your ec meter is not well calibrated ✌️🏽 Hope to be useful and clear in my bad english 💪🏼
