My RO comes out with PH 6.3. If I add Canna AB 16-18 ml/ 10 l and 5-10 ml/10l Rhizotonic, I end up with PH 6.0 without any adjustment. I try to keep the PH around 6.0. If my PH meter is off, I´m still in the adequate range between 5.8 and 6.2...
You didnt read what was posted...
This is what my Nutrient label says...
What if my pH is really high?
If you pH coming out of the tap, or after Reverse Osmosis is still about 8.0
, we suggest that you using pH down and adjust your water to 7.0, then mix Supernatural Brand Nutrients.
Certain mineral’s will not dissolve in when the water is too alkaline. So it best to first pH your water to 7.0 then mix.
My tap water comes out ph@9 so I need to ph before I add my nutrient...if my ph out the tap was 7 or under I would not worrie with ph before only after.
I know this is an old thread but some times it will help to ph before and maybe after adding your nutrients
