off gassing?

First off this is not a nutrient problem. I use the same res to feed other rooms and they are perfect.

The difference in this room is I have a bigger dehumidifier that goes on and off more often than my other rooms.

With in a few days of putting plants into this room the leaves do this. If I take them out they recover with in a few days.

I have run out of ideas. Could it be the mini split? I doubt it because all line connections are outside this room.

Bump. You're the second person posting pix that look like this, can't remember who the other guy was, though.
