Phal with fluid dripping from leaf . . .

[JesseGirl]

Hello All!

I have a 2-yr-old Phal that over the past few days developed a moist yellowish spot on the largest leaf. Since last night, I has started to drip fluid from this one leaf. The spot seems to be spreading and the texture of the leaf in the discolored area is soft but dry.

This plant has been healthy. I just changed it's location approx. 1 month ago and since moving it, it has developed one new leaf and a new flower spike. I think it is happy here, but now this drippy leaf!

Is this a disease? A pest? Or is it perhapse just a natural aging process?

Any help would be VERY appreciated (especially b/c I thought this plant was extra happy and getting ready to bloom!).
