idk...this is quite wierd...i've never seen just one limb do this...couldn't be over/under watering...this plant gets feeding every other day...it consumes alot and is very light on every 2nd day. I watered it today and no improvement.
no injury to the limb...very stiff and very much attached to the main stem...i do have pets but they are small dogs and i don't suspect they were grabbing on it....the whoe length of the limb is limp...very wierd
