So the ro system didn't come today. 2 of 3 got Rez changes though. Did half of what gh says for there nutes 4 ml each of micro gro and bloom 2 ml of Cal magic and a sprinkle of orca. In 3 gallons of water for both the green crack and strawberry banana grape. I only had two buckets of water that had been sitting for 24 hours so I will do the white widow tomorrow night. It hopefully the ro system comes tomorrow and I'll do all three over again since my starting ppm out of the tap was already 180. After what I added it was 420-430. Hope this helps them. The roots looked a little brown.
