Hey everyone. I've had an indoor palm plant for about 6 months now, and recently it became quite sick. It had brown, sticky bumps on the top of many of the leaves. Also, some of the leaves were brown, dried, and dead. The floor below the palm was sticky, as was the wall beside it.

Using a damp cloth and warm, soapy water, I cleaned every leaf with gentle rubbing and was able to remove all of the brown, sticky stuff. Unfortunately, it slowly came back. Thus, I cut off the infected branches.

Now, the ends of many of the leaves are turning brown and drying out. Here're some photos of the palm:

Help! What should I do?
