Stinky Phal roots in FWC

[Keiki Paste]

I purchased this Phal from a local orchid grower for $10. I immediately put it into full water culture. I kept it in my window at work and began to notice a foul odor. None of my other fwc orchids have any odor at all.

I cut off what I thought were the culprit roots two weeks ago and the smell has persisted. Today I cut a few more, and doused with straight hydrogen peroxide, twice.

I can still smell it, but not as strong. As a newbie, I'm not sure if this is a lost cause. It is growing new roots and has not suffered bud blast, which tells me that there is still hope as long as proper action is taken.

Does it look like a disease? Is it only a matter of time? I have it drying in a glass...

Edit: I finally attached photos! I'm going to have an extra ice cream sandwich tonight!
