The problem plant does seem to drying out slightly quicker than the others. The surface is actually still a little most, but when I felt the soil within the drainage holes, it felt almost bone dry at the bottom. This is also the smallest plant, so it is possible the roots have not made it to the bottom of the pot. Here is the pics. Both of the brown spots, and other the drooping plant.

Like I said, Im certain this plant has not been over watered, so what could be another cause of drooping? Its the one in the 3rd and in the back of the fourth pic.

The plant is located in the back of the room right now. I got 3 plants up front, 2 in the back. It in the back, not very close to the fan.There is good circulation in there, but its not near the intake fan.
