I using CO2 burner .. What i heard from everyody is that if using co2 best temp is 74 degree because when it 78 degree they closed up i forgot what it called .. they coed up to hold water in plants wont let co2 in .. @ 74 or below with co2 get the best result because when it little cold they open it let water go ... is that true?
Areo VERY SICK PLANTS ANY IDEA < PIC PIC PIC >

What you are talking about are Stomates. Think of them as air vents in the leaves that allow respiration. If it gets too hot out, they close up to retain moisture. If the stomates are closed and respiration is not going on, the plant is basically in limbo. Very little to no growth occurs when the stomates are closed. There are those who say that room temps can be a bit higher with a properly CO2 enriched environment, but the operative word is 'properly'. Unless you have the room set to enrich, hold for xx minutes and then purge, it is not proper. Another common mistake is running the CO2 enrichment when lights are off. CO2 is best utilized with lights ON. Normal outdoor background CO2 levels should be about 330 ppm on average around the world. If you can get your room to about 1000-1500 then that should be plenty of CO2. If you are using a CO2 burner make double damn sure you have carbon Monoxide detectors in key locations as well. Sorry if you attached a pic, as I sure don't see it, other than an avatar pic which is too small to discern.

MacGuyver is absolutely right on the money. with co2 peeps usually run as high as 84 degrees. i also was researching about your problem, if your water flow deepens and slows down it can over water your plants weird huh? but makes sense as the roots grow they block water ways.
now that i was thinking about it when i had an aero flow 60 i had to lower the drainage tubes all the way down and angle the square tubes that hold plants towards the rez too speed flow.

Also your humidity is pretty low.

your ppms is ok so not nut burn. but over watering can lock out micros and trace minerals. prob what happened.
when you raise a/c your humidity prob will rise a lil due to compressor turning off for a bit and not dehumdifing your air giving the room time to build back up. thats what i noticed with my a/c

If you have a robust and effective root system then low humidty should not be a problem.
I think it to be almost impossible to overwater in hydroponics much less in an aero system. Considering in an aero system, H20 is your growing medium.

true that... i dunno then unless like i said the water is to high in channels and not enuff air to water ratio with little movement.. hmmmm dunno

He's saying he is using all AN nutrients. I'm not sure how and what he's specifically using, which could help to pinpoint it mainly. Most likely an overload of hyped up cannabis-specific nutrients, an imbalanced mixture, or a build of of salts. Either way I think the best bet is to flush, re think what your giving your plants, and go back to the basics of horticulture.

word a build of salts for sure since AN does run a lil on the hot side.

prob only have to flush with 1/4 strength nutes and be fine.
Now 2 days flush with 0 ppm water - they got better than it was . GOT MORE greener ..... I just changed water . What i added in
WATER @ 0 PPM
CAL MAG PLUS @ 100 PPM
SENIS A & B BLOOM (AN) 650 PPM
ALMOST 4 WEEK FLOWERING......... SEE THE PIC WHY LEAVES DO THAT AND WHY RED ON LEAVES STEM ? ANY IDEA PRO? THANKS

but now back down ... To a & b alone till it get better ,,No it not too low it get 50 at night 42 day time ...

Good pictures this time, helps a whole lot. If it were me, i'd still be flushing. Not sure exactly what you did but the root systems are gone. There's where your problem lies. No need for nutrients now, not like your plants are going to uptake em' to well anyways. Keep flushing and hope that you still haven't completely fried all salvageable root fibers. The red stems are usually genetic but could be necrosis effect of uptake unavailability.
I think PH keep playing me ... the ph been rough lately ....
