I agree with the previous post about O2 vs. CO2. I oxygenate the roots and give the CO2 to the leaves only when the lights are on. As Im sure you know this, you might have gotten a bit high tech for your poor plants. IMHO I would save the "special" CO2 and just put a couple of small sugar/yeast reactors in with the plants during the light cycle. Someone else said it before, but CO2 is one of the last things to worry about. Get a system down pat, then add CO2. Trying to create "the best system" is what we have all tried to do, but doing it step by step proves to be more fruitful in the end. Keep your variables to a minimum and don't buy "special" CO2 when you're stoned
LOL!,well thats one concept man. Hi all,sorry I aint kept you`s up to date,PC probs!

Well... shes not dead, Ive stopped the co2 and the h2o2 and kept a close eye on the PH and shes still showing slight symptoms. Every time I try to up my ppm, it gets worse,then the ensuing 48 hr flush. This is a strain I am really familiar with so its fair to say I know this plant and how it grows and NEVER before have I had a falling PH ? Could this be due to limescale/salt build up in the tank? The tank and tray has a textured surface to it so I can never get it up to shop fresh finsh when I clean it, heres some pics any way. Peace, RM.[attachment=o211437]
