Sudden fungal/bacterial attack on my Vanda in spike

[cuckoo]

Up until a couple of days ago, my newly acquired (a couple of months) Vanda (Rapeepath yellow) was doing fine and appeared healthy, growing fat new roots (in its new lava rock medium) and steadily developing a spike (after several years gap going by the position of previous spike stubs) and I was pretty pleased with myself It did have tiny black/purple spots, mostly at the leaf edges and then on the spike as it poked out. I have been keeping it in an east facing window and outdoors depending on temperatures and rain (indoors when it gets too cool outside or rains too much). Anyhow, it is now showing big watery orange spots on too many leaves to simply cutoff. Even a fat new roots suddenly became brown and soggy. I have cut off the root as close to the the stalk as I could reach (most of the remaing part was green except a slight portion). The wet spots were oozing yellow liquid on the leaf underside in some places. I wiped off the spots, sprayed hydrogen peroxide on the spots, wiped off and applied/dusted off with cinnamoned powder. I just ordered physan but it will be afew days before I get it. I will add some pics in the next post. Please suggest best option at this time.
