Refilled the reservoir with a new batch of nutrients using the RO water. The plants are loving it already. 600W HPS + 600W MH drip system on rockwool for now. Right now I'm just growing out some Ak47 and Skunk #1 until I can take some clones, then I will flower those clones under 1200W HPS + 600W MH in an ebb & flow. I am going to need a lot of good water, and now that is not a problem.
