Hi, my beautiful Pink Lemonade tropical hibiscus has had this issue for a couple of months now. I keep thinking it will heal back up and become fully green again, but that has yet to happen. Little to no aphids or pests present that I can tell. Any ideas on why the leaves are doing this? It's usually only 2-3 leaves at a time while all others stay green.
Thanks!

Those black spots made me think fungus so I googled it and up came this article. I hope it helps. The article talks about winter but maybe your conditions have been too wet even in summer. http://www.hiddenvalleyhibiscus.com/care/leaffungus.htm
