I posted this on another thread but I also added it here on my own thread to see if anyone else is having or had similar issues. Im experiencing this problem at the moment! I built myself an RDWC and a tankless water heater hooked up to co2 controller, the first grow it seemed to do ok but not great, this grow im getting stunted leaves, calmag issues, really bad purple leaf stems and purple stripes up the main stems, it seems to effect the plants opposite first (first contact with the gasses from the burner?!) I have tried venting at night and a few times during the day but these problems persist until I cut the generator completely and switch the vent on! I have a CO alarm in there which never registers anything. What really confused issues is that I had a PH pen issue at the start and was running PH too low, when I realised this and corrected it I had hoped the problems would go away, but they just got worse! I found a few posts on the burner issue and after running for a week or so without the burner the plants were doing ok again, not perfect as im not getting the fan leaves that im used to, they all seem thin fingered if that makes any sense? My single pot is doing much better but what I did notice is that with the burner on, any roots above the water in the big system slowly die, only the submerged ones seem to survive. My environment is pretty dialled in! RH 60% temps a bit low at 22 but I blew a ballast other day and am waiting for the new one to turn up so I only have 1 light on for a few days, I have added an aquarium heater and all fresh airstones as I found a couple of them seemed to be blocked and the water was a little cold, ive got it up to 21°c now. This problem is driving me crazy, Im thinking about ripping the whole lot out and going back to simple single buckets next grow. In the pics you can see since turning off the generator im getting nice new root growth but it still seems like they are growing slower than they should be too me, In my single bucket dwc tent grows I had a job to control them they grew so quickly!
The single red bucket (first 3 pics) was a cutting I put in after the others and its doing great, big normal fan leaves but the big system …...I decided 24hrs ago to seal her up and switch generator on to make sure that's whats causing it and 24hrs later....cal-mag issues, purple stems getting a lot worse and this strange leaf curling and stunted growth, the fan leaves are much smaller. The older roots look stained but they are not slimey and dont smell of anything, although they do seem very ropey, not many feeder hairs. Anyone able to shine a little more light on this before I explode lol.
