Thanks for the help,they seem to be doing a little better.They have a lot of new growth,but it is very light green and the plant is darker green.I think the really good watering helped.They really never seem to be very dry and the room is never hot,I wonder if I am really underwatering them.I have tried to be very carefull about this but I could be a little rusty it has been 10 years since the last time I did this.
