oncidium drooping leaves

[articoasis]

my oncidium has bloomed and flowers have fallen off three weeks ago. now the leaves are starting to droop. they are still very green and i see new growth. any ideas.
the orchid is in large east facing window. temperatures have been in mid 70's to low 80's. humidity 60-70. I think I may have overwatered it. when the leaves started I thought it needed more water. I unpotted plant and it was potted in saph moss. I cleaned roots which were very dense and really wet. I repotted into bark and perlite in a basket type of pot to try and dry out roots. it was very hard to see if roots were bad as there were very wet. I did see some green ones but most were whiteish color. some of the leaves are now splitting down middle. the leaves are very dark green and not wrinkled. I see two new small bulbs growing and new leave growth which are not drooping. any ideas
