Ph And Organics? Help

OK,my RO water comes out 6.8, when i add my organic nutes it drops down to 4.4,if i try to buffer the PH up(organic ph up)it takes my ppms over 1200.I raise the ph up tp 6.5. What should i do?

Do you have really bad tap water, and that's why you're using ro?

What fertilizers are you using?

Tap is kinda high. Roots organic,fox farm soil

I see, I'm not familiar with them. yet if you are growing all organic pH shouldn't be much of an issue, as the biodiversity in the soil should buff it to what the plant needs.

fox farm soil will burn ur plants

If the pH Up is organic you can use a little bit of it but you don't have to be so concerned with getting it to be right at 6.5, just over 5 should be great. All you might want to do at some point is work some dolomite or calcitic lime into the soil and that will keep the pH adjusted.
