Hi bro thanks for your time.There is no fresh air intake at all?
I run a sealed... Tent but it still sealed I know because my air pressure is a daily fan adjustment. That tent only breathes through the intake. You can filter the intake and add an inline fan, then you are still effectively "sealed" light, bugs, particulate etc. but your girls can breathe!
I'm not sure what exactly the issues are here, theres a lot going on but I would consider lowering your e.c drastically while you get a handle on this.
Hi bro,Do you need epsom? Are you not getting enough mag with your calmag? Excess mag will lock out calcium and potassium.
Hi bro, thanks for the response.I don't think it is off gassing. How much epsom are you using?
Im a soil grower who runs sealed, and Ill try to help.
Looks like a nutrient/pH issue to me.
Ill read it again and see if I missed something.
Regular sheetrock or what for the walls?Hi bro, thanks for the response.
I have a vented room next door feeding the exact same nutes with pretty much the exact same temps and humid but only difference is I’m using a intake fan from outside for fresh c02 Instead of bottled. This room is 100% healthy and thriving.
I have raised lights today and dimmed half to 250w and half to 400w, I’m not getting any Large fan leaf curling though which I’ve had before due to heat/light stress which makes me think it is not a light intensity issue.Can you reduce light intensity at all temporarily?
3 of the walls are brick insulated walls the other is a plasterboard wall insulated with 100mm cellotex, the whole room is black and whited with all gaps foamed and taped.Regular sheetrock or what for the walls?
Paint?
In theory. I'm not sure on this one bud. Might just be too drastic a change from one environment to the next. Maybe a middle ground environment in the short term to allow them to acclimate.?? Sorry. You'll get what you need for info here, someone knows better than I lolHi bro thanks for your time.
I have an exhaust fan set to come on if temps get above 32c(Ac fails) but no intake fan. I supply bottled c02 through a controller to regulate my c02 levels in theory I shouldn’t need a fresh air intake.
Yes partially this. I agreeIn theory. I'm not sure on this one bud. Might just be too drastic a change from one environment to the next. Maybe a middle ground environment in the short term to allow them to acclimate.?? Sorry. You'll get what you need for info here, someone knows better than I lol
Hi Aqua, thanks for taking your time to have an input.Higher humidity is ok to ease stress but you also need to lower the light intensity or the transpiration suffers. I should have added this to the post I linked but hindsight is 20/20 I took for granted light intensity was optimal.
What I do when I see plant stress in this order.
Lower light intensity first and foremost.
Raise humidity to the lower range of KPA recommendation for stage of growth.
Find and correct the issue before increasing light intensity or KPA then slowly work back
They literally had no transpiration in those conditions. I think the VPD is the main culprit, exasperated by the light intensity.Hi Aqua, thanks for taking your time to have an input.
I have just done all these and will post up results (if any) in the next couple days. I’m running the TrolMaster controller with full control of all environmental factors so should be able to dial the points you’ve made fairly quickly. I’m guessing I’ve just super stressed them out from going to such extreme condition change.
