I acquired a bunch of orchids and I am learning--slowly. I have been nursing this particular phalaenopsis and was happy to see new leaf growth over the past couple of weeks. Today I found this black rot (?) on one of the new leaves. Please help me identify the problem and teach me how to treat it. Not sure if it matters but I live in northern Florida and I keep my plants outside. I try not to over water but this almost looks like water sat on the leaf.
Thanks in advance!
