I use the local well water for hydros, PH always higher than 8.5, I use the Glacial acetic acid(same as vinegar but higher concentrations) to bring down the PH, but no matter how much acid added in or no matter how low the PH level I got in that moment, few days after the PH level back to original that higher than 8.5.
I grow with the 20Liter DWC system by the way.
ANY HELP WILL BE GREAT, thx
