I will throw in the last few lines here...
This is what I figure, initially the plant was growing well until the roots got a little too soggy. This will cause the leaves to droop due to stress. Recently I did a bad job on one of my Helen's Hybrid sdlg with a compact media and it went dorky like your case. Being in an enclosed environment, it's heaven for a lot of critters to hang around.
Once you have all the things sorted out and its outdoors, the airflow should take care of the rest.
All the best!
