morning, i've had plants (indoor) where in the middle of the plant the main stem seemed to have dried up, the stem itself became woody looking while the rest of the plant above and below this given area remained green and healthy..
Leaves dried and fell off almost like a stem rot without the rot part. On mine I ended up cloning (topping) the plant above the "damaged" area and allowing the lower portion below this damaged area to continue to grow out..
I did notice on a couple of clones (namely an AK47 clone in my last session) this damage seemed to move down the stem and follow the path of a branch, though movement was very very slow it did seem the damage whatever it was continued through the plant.
This may not be your prob although the browning of the stem sounds like it..
I hope it isn't and wish you luck in figuring out what your prob is, as mentioned filling out the questionaire would be more helpful along with a photo
