I have a chiller on the system and I would say it stays around 66-67 degrees round the clock.What's your water temp? Does it drop during lights off?
i appreciate your efforts EventHorizan!Has this only been happening since you started using co2? Pearly white roots? Have you checked for any larva or bugs in the roots? You are showing nute burn but I don't think it's from too much feed. I think something else is happening... What I'm not for sure. But I'm tagged in this till you or someone figures it out...
I built the rooms about 18 months ago and have never ran the rooms without it. I always wondered if the build up of co2 at night could cause an issue. But never thought about use of co2 in general. I veg with co2, then when I flip, I run it at 1500ppm for a couple weeks , and then go down to 1200 and so on till at week 8 I am at 7 or 800.Has this only been happening since you started using co2?

Do you have a way to check c02 levels at different places? I think its c02 related. but that is just my gut with really no factual basis!I built the rooms about 18 months ago and have never ran the rooms without it.

Yes , the roots are fine.
I am actually done with these two runs but would like to pin this down and try to fix before the next flip.
I have a few pics of the room. let me see if I can find a decent one to post.
This problem seemed to start when I installed the enviro controller. The sensor for co2 is now in the middle of the canopy where it used to be on the wall. The room may be getting more co2 now. Definetly something to think about.

btw your garden looks great. I can see you have invested some quality time into it....I built the rooms about 18 months ago and have never ran the rooms without it.

what was your comparable gpw between having it and not? Seeing that it effected stretch and canopy? Prob not much since you got de ballast.In the last two pictures I forgot to spell out what I was trying to show. without the controlled environment , I had a lot more stretch. More compact in with the enviro controllers.

I lost a wopping 4 or 5 units from one grow to the next. Until the enviro controllers, I atributed the stretch to the co2 . if we are right about too much co2, after 1500 more isnt better .what was your comparable gpw between having it and not?

No from what i understand too much will harm them. Im thinking your co2 is reading is not an acurate measurement of what the room really is. How is your air circulation IN the room? And do some plants is certain parts of the room have itr worse? Towards the middle? Right under lights? Back by wall? We need as many clues as we can figure out.I lost a wopping 4 or 5 units from one grow to the next.

Before the enviro controller, which i assume is controlling your c02, what did you have to control c02 release and measurement? And do you see yourself using more c02 now than you did before the controller... Im so interested in figuring out what it is. I read another thread somewhere in the last 6 months with pretty much the same problem. Op must of gave up on the thread, and no conclusion was ever shared....
