Cugine,
I am not sure if it was the lighting or what. So maybe what I think is totally wrong. But those roots look terrible to me. They have a bad golden color to them. Mine are always a pure white color, with fuzzy little roots coming off of them. Are you useing anything like Hygrozyme, or maybe Sensizyme. I think you plant is freaking out from root rot starting. Get you nose right down on those roots and take a big wiff. I really hope I am wrong. I will be most happy if so. I have heard that Voo-doo juice does even better then the two items I talked about. But it cost an ASS load of money. like $90 a small bottle. But you can find it for $54 on the web. I am thinking of useing it once I run out of my Sensizyme.
Good luck on your recovery.
