your just plain wrong if you do not have adequate things to add or experience please dont it only spreads confusion. those pics show light bleaching period and maybe also a cal mag iron issue. i grow in the same tent i have for years when moving to a bigger light i experienced these symptoms going from t-5's to 600watt hps. i have over 440 cfm of air moving through my tent as do most explain how your theory is even remotely possible even with the worst materials available do the math silly theory lol.
No actually,
you are completely wrong. Dont trash people when all they are trying to do is help, and then act like your the high and mighty know-it-all.
This was a toxic tent produced by Hydro Hut which leaches chlorine gas when the temperature reaches approximately 85 degrees. It has to do with the type of white PVC lining that was used inside the tent. The tests used to initially establish toxicity of the material were incorrect for the application, human sensitivity to the gas is exponentially lower than plant sensitivity. Hydrohut shipped hundreds, probably thousands of these tents to market, and first blamed the issue on the metal frame (which they incorrectly recalled) before finally owning up to the fact that they had done a piss poor job in quality control.
And regarding your airflow point, I had a 435cfm exhaust fan running at maximum capacity at all times, combined with a 200cfm intake fan (+ passive) and a 3' tower fan for circulation. it. did. not. matter. at. all.
I switched the tent out to a brand new GrowLab of the exact same size. Using the exact same equipment and procedures I had zero problems.
Solved.
