Partly mushy brown leaves on Trichicentrum

[nzadro]

The saga with this orchid continues. This is Trichicentrum Tigrinum.

There were unidentified bugs on the mount. I soaked the whole orchid in water and small amount of dawn. A method some forum users use and I figured it would work here. Hausermann still has bit gotten back to me to suggest what this could have been.

Unfortunately, since this is still an immature plant (about a year or so from BS), it is not faring well. The bugs are gone but well, at what cost.
The leaves has slowly turned a dark brown green. They are oftened but not squslishy. The tip of the rear leaf is totally mushy, but the green is still stiff as it should be. The base appears to be green... it is had to tell in the images. Roots are visibly unhappy.

Did this turn bacterial infection? Or just waterlogged from drowning?

I have it isolated for now but I am sure itd be happier in my humid warm terrarium. If it is a goner so be it, but Id like to do what a can.

Thanks
