Hi ecrane3. Thanks for responding. I've posted 1 large picture that contains a "before" pic showing it full and healthy (left pic), and two pics from this morning :-(

Since the summer, the temperature has dropped around 10 degrees in the house and is now around 65 degrees (I put the heat up today a bit as I wasn't sure if the the temperature was the problem). In terms of watering, I wait until the water has dried before I water each time as per the instructions that came with it. The humidity has dropped about 10% to around 30% right now in Colorado - it's really dry. I'm not sure about the pot size - perhaps from the pic you could let me know if it's ok or too small.

The drop in growth and loss of leaves seems to have coincided with the winter coming. New growth is very healthy though - but they don't grow to the full size and deep, rich green colour that early growth did - and brown/die very quickly.

Thanks so much for any help you can give.
