0.8ec is heavy water, you might find you get some issues in flower. id add a water filter to that mate. that means your base will be 1.1ec before you add any feed. you will have to see how it goes but id be adding an RO filter even if you mixed half and half tap water and RO water. Do you drink that water? Its not good quality, hard water with low ph.
one thing though 500ppm isnt 0.8ec, it would be 1.0ec. what type of meter are you using?
