Looks like lumen shock lower your co2 and raise your lights ....
It think it's the temps coupled with low humidity. Just because your sensor says 83, doesn't mean the leaf temps are the same...leaves are dark...your sensor is more then likely white....and your sensor doesn't measure radiant temps...just the ambient temp. Lower your temps to 80 see if that helps, or raise your lights.
Do you have a fan blowing on the plants?
How close is it and what speed is it set at?
How high did you move your lights up?
I don't know for sure but I don't think dropping your co2 will help
the canoe, I just don't think the canoe situation is allowing the
plant to take full advantage of the co2.
I get temps into the 90's on my one thermometer and my top leaves don't canoe
like that. They did though when I had my light about 12" off them
and a fan blowing across the top of the canopy.
It was like they were losing too much water from the heat and fan
and attempting to close up to slow it down.
I moved the light up to around 18-24 inches and lowered the fan speed
and the canoe hasn't returned. (only running a 400w though)
edited to add I'm running a vertical parabolic vs air cooled hood..
Dude if your growing OG's it might never go away its a trait of that strain....i would worry if they didnt curl. lets see some better pics
Humitdy is way to low....1 I'm in veg
2 co2 1300ppm
3 temps 80-83
4 humidity 35
5 pH 5.8
6 Formula General Hydroponics
7 Problem started when I move them into #2
8 6" top feed rockwool cubes
9 water when needed (pretty much once a day)
Note: weird thing is its not happening in my #1 room (veg room). transferred over early into #2 because I needed space (still 18 hours). curious thing is, the problem is only 5% in #1 compared to #2. I thought it was humidity so last night I raised the humidity to about 42%. The problem did not seem to get any better. What do you think?
Humitdy is way to low....
