DO you have to PH RO water alone?

Not sure--it's used a lot in chemistry applications requiring water if that helps. You can prob find some online...
 
RO water is water that is filtered to a Reverse Osmosis Membrane. RO water is 99.99% pure and generally the ph does need to be checked and adjusted. the filtration process normally lowers the ph (i generally see a ph of around 5 with ro)

thanks, i have always been ph'ing it up , but someone told me i dont have to when not feeding as there are no nutes to take up, i did think this was incorrrect.
 
just try to mantain a steady ph leavel when you feed or water and out the drain.( runout ) if you have a soilwith no ferts in it you will mantaine the ph a lot beter and not burn up your plant.
 
the ro i use sits at about 6 to 6.2 so i dont adjust much for soil. once youve added your fert line you may want to check again to see if it has changed significantly. ph is logarythmic so one point change in ph is a ten fold increase or decrease in acidity or alkalinity.
