I Need Help with Ro water

Hi guys , just got myself an Ro system and I'm wondering where to sit the nutrient strength.

Currently I'm feeding tap water that's 0.56ec
The Nutes I added to the tap brought the EC to 0.69

My question is once I start running the Ro system where would I put the EC?
Do I keep it the Same as it was or would I have to lower it?


Thanks

I think youl tell me to keep EC as is but I have to ask either way.

Maybe you don't understand my question..

I've never used Ro water before , when I start changing out the Dwc buckets for the good water do I replace what the filter took out the tap water with nutrients.

Dwc Res right now 0.69ec with 0.13ec being the nutrients

After i filter the tap water I have 0.01ec so would I add 0.68ec of nutrients?
I just don't wanna make any mistakes.
