Low RO water

Hey All,

I have a question I’m growing in soil and using Mills nutes. I have been adjusting the Nute water to 5.8-6.0 as directed, When I test my RO it comes out 5.2 all the time. Where am I going wrong I mean the plants look nice and green but I know 5.2 is too low or is it ?

Don't worry about runoff PH.

6 is the low end ph for soil. You should be aiming for 6.5. I believe mills 5.8 to 6 recommendation is for hydro.
