I’m growing in ocean forest soil & roots organic 707 & I’m using RO water. I’m adjusting the pH every single water anywhere between 6.3-6.6. I have not given them any nutrients because I’ve never had to this soon in the past but now that I switched to RO water my plants are yellowing. Can anyone tell me what I need to do to fix this?? I even brewed up my roots organic terp tea 3 times this week at half strength and I have not seen any changes at all. Should I be adding cal-mag every watering??? Thanks.
