White powder on indoor palm
I have a palm as pictured below and I noticed a lot of the newer leaves were turning brown, so I did a close-up and noticed tiny little white dust like particles literally all over the plant's leaves. I also noticed some webby material, like cobwebs. I was horrified and immediately took the plant outside. It is currently enduring 40 degree nights and 70 degree day temperatures. I feel bad about deserting it outside, but don't know what to do about this problem. I can't use any toxic chemicals. This palm has two NEW shoots coming out, so I know the plant itself is healthy despite this mite, dust, whatever it is. Please help me save this plant. :( What do I need to do to save it? Thanks for any help.
