I take back what I said about transplanting. You are already in pots that are too big for your plant. If you try to transplant now you will just shock the hell out of the plant and it will get worse. Follow the flushing guidelines.

Be sure to drill additional holes into the sides of your pot to help with drainage and aeration. This will ensure your roots don't drown.

Also I still can't tell if that's an air cooled hood or not. Either way you need to be exhausting the room.
