Problem with anthurium
I received this anthurium as a gift in the mail from 1-800-flowers and it was subject to some cold temperatures due to a storm-related delivery delay. A lot of the leaves turned brown and died, but there are still a number of small leaves on the bottom. Most seem fine, but one has some flaky, chunky white stuff on it (which seems to be stable and over the last week, has not increased much at all). It looks like table salt. Is this a mold/fungus, or could it be a bug? I have other plants, so I want to throw it out if its a bad bug infestation that could get to the others, but I don't want to give up if its salvageable. Any help is appreciated! Thanks!
