I have an anthurium. It gets sun from the west window. The leaves turn brown on the tips and then it spreads throughout the leaf until it falls off or I pull it off which when I do it comes out easily after the leaf is totally brown. The plant continues to grow new leaves but even the new leaves have this happen. I keep it the soil well watered and do not let it dry out. It also gets what looks like tiny spots either tan or brown which I am able to flick off with a finger nail. There are no legs so I don't know if it is a bug? They are oval shaped.

It may be that it is getting too much water and the spots sound like scale. Try touching each one wit a q-tip dipped in alcohol. Check http://www.hawaiitropicals.com/anplancar.html for more information.
