Help my plants in my sealed room

[soaringfast]

Recently I have had some real strange problems with my sealed rooms.
I started to use cheap blow molded pots that smell like laundry detergent.
I take beautiful vegged plants and put them in these cheap stinky pots and put them in the sealed room where everything is perfect.
With in hours the leaves droop like a sign of over watering but they are not.
With in a few days the new growth is yellow green like the pictures.

If I take the plants out and put them in a unsealed room they snap right out of it.

Is this a sign of off gassing? In the sealed room the poison has no where to go. Btw both sealed rooms are doing this and this is the first time I have used these pots in these rooms.

I dont know.... but those leafs look pretty cool looking.

Do you have Co2 in that sealed room??

it kinda looks like a later stage of magnesium or manganese deficiency. not sure though. what are your temps? sometimes you get mg deficiency cause your root environment is too wet and cold, or too acidic and cold.
