Becca, I'm sorry to hear that things did not clear up. When my Aerangis developed a brown spot on its leaf, I tried to stop it from spreading. But in the end, I panicked because the spot was quite close to the crown and ended up cutting the whole leaf off. See the thread: http://www.orchidboard.com/community...-aerangis.html

Its now growing a new leaf and seems to be doing fine - so I'm sure your's will be all right too.
