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.Over/under watering, maybe some slight N deficiency?
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 wierdany sign of injury on that limb? got any pets. is the whole length of the limb limp?
