Please see my website, http://www.jimcraft.us/Sick%20Phal/index.htm: This
condition has happened to my Phal 2 or 3 times. It sits in an East facing
window with plenty of light no direct sunlight. Humidity around 50 to 60
percent, temperature 70 to 73 degrees. It is watered regularly and fed at
least once a month. I can get rid of the white spots by gently rubbing them
under room temperature running water but these spots come back after a week
or two. Can anyone please help me with this problem?

Thanks,

Jim
