Christmas Palms have brown Spots on leaves...HELP!
 

I just bought a bunch of xmas palms and foxtail palms.. I went out of
town for 10 day right after buying them and a friend came over and
watered them while I was gone..

They all have brown spots on them now.. The foxtail has a brown
coating on the stem. I don't know it that's normal or not so I took a
picture of it too..


I live in Miami Florida ..

Here is a link to all the pictures.. Click enter on the website to

Please help if you can ...
