What nute regimine are you using and have you calculated that the intellidose is correctly dosing said nutrients?
I
Im going to guess lumen shock. Something is keeping the plant from producing something it needs for photosynthesis. Have you tried turing off 1/2 of the lights for a few days? What was your light start up procedure? Did you start them in their MPB's with all the lights going? Did you add a little N in the first week and 1/2 (foilar is best) of flip?
They look hella stressed and need a little less light :)
Wrong, our CO2 is set at 1200, seems to stay around 1300 though. It was up high today because our power failure occurred and no circulation was happening, thus the 1500 misread. Should we lower it below 1200?
I've never ran CO2 in a sealed room before so that definitely could be the thing we're screwing up on.
I was theorizing that with so much CO2 and so many lights, the plants were using more nutrients then what we're used to seeing, thus creating deficiencies and lock outs?
As you guys can see, we're fucking frustrated so thanks so much for the help.
You have a salt build up inside the plants caused by overfertilization (lock-out), resulting in burnt, crispy leaves showing a deficiency in N,K, calcium and magnesium +++
Most likely it is your nutrient concentration, plus the PH you are running.
With the Sensi A&B I would start with the lower 600 ppm dose. Check their charts, I believe the 850 ppm you are running is for advanced, aggressive growth.
Also, back off the times on the waterings a bit for a while. The plants will suffocate if kept too wet while recovering from the lock-out. Use a root stimiluator and some B-1 and not much else until they show good root growth. Then start with your fertilizer program.
The effected leaves won't get any better, they will eventually die off.
But the new growth will be all good and overgrow any older burnt-up stuff.
You gotta wait and be patient. Don't spray foliar feeds, you will only burn the leaves more.
