As the title implies, I think I'm screwed. In the interest of full disclosure I bought a phal that was planted in the god-awful sphagnum moss (awful, that is, for this plant) and transplanted it - while still blooming - into a bark medium. I probably shouldn't have done that.

In any event, related or not, one of the top (and thereby younger) leaves of my still in bloom phal has a segment along its main vein that is broken open. Light can get through though it's very thin and, until now, was unnoticeable. The margin of the broken segment is slightly yellowish. I assume that this main vein is critical for the transport of water and nutrients and that my plant is doomed.

Please advise. I will nothing unless advised by an expert.

BTW: I water only once a week. No more. I know that less is more with water.

Thanks.
