I don't have a thermometer but I drained down the tanks quite a bit and added cold ph'd water. My ppm now is 800-900. I also removed as much bad roots as possible. I also lowered the water level so they can breath better. Not sure how much 3% peroxide to add though. I'm afraid of adding to much. I'll go search the archives some more.
moreover123 Reviewed by moreover123 on . Bubblicious Problems - Root rot? This is my 2nd grow. First grow was 1 NL x Shiva and a WW. Both came out nice but the WW was outstanding (IMO). 4oz off her. I didn't have a TDS or PH meter and rarely checked pH with dip paper. So now I have Bubblicious. Bought the meters. When I went to 12/12 one week ago, I used the GH chart (I have GH nutes) and was at 1100-1200 ppm with ph at around 5.6 ish. 400 HPS w/430w Hortilux. I have a bubbler system. First off, the plants are much spindlier this time. But the real Rating: 5
