Default bacterial leaf spot?

hello,
reRooting 2-leaved 3-rooted phalaenopsis
had brown liquidy spot on (a now yellowing) leaf (has been in a plastic
bag and recently WAS growing several new roots (also has a VERY SMALL
3rd leaf))
i cut out the spot (after cinnamon and rubbing alc. swab (TINY drop of
alc ran towards crown)
changed the bag and its dishes etc...and dusted the media w/ cinnamon
i have no access to orchid antibiotics etc so used cinnamon....
QUESTIONS:
1. in my book a leaf burn looks similar to the spot (although the spot
was liquidy) (the plant is under fluorescent bulbs -- have turned off 1
of the bulbs but wonder whether i misDiagnosed the spot as sunburn
(lightBurn) especially in view of the fact that this leaf was being
shined on whereas the other was more shadowed and is still darker
2. is there anything else i should do?
ALSO
3. i had been given an oncidium which several people said had a
bacterial infection (via the internet) and i wonder whether this could
be the same bacterium?
(it was never touching the phalaenopsis)

PLEASE ADVISE
thanks very much in advance
p.s. this little phalaenopsis means a lot and i don't want to lose it

Default bacterial leaf spot?

Phalaenopsis leaf burn will not be wet at all, but will show up as a papery
patch. It definitely sounds like a bacterial or fungal infection - or both.
If the leaf is yellowing, remove it in its entirely.

Default bacterial leaf spot?

hello Ray,
i greatly appreciate the advice however i wonder whether you would be able to
look at its photos (today's) since the leaf looks if not better, at least the
same...
just wonder whether the leaf looks like it is harboring bacteria / fungi or
whether one can tell....
also i have had it in a homeMadeGreenHouse (plastic w/ water below its container
to increase humidity) and when i noted the spot there was condensation
throughOut the bag and plant (and on the spot) and only several days later did i
find something on bact leaf spot -- that's why i cut the part out (it had not
spread or anything)
also if you feel i should remove the leaf WHERE do i cut it?
(this will leave it w/ 1 leaf and the baby leaf -- is that enough?)
finally: could this (i believe it's a Pseudomonas that causes bact. leaf spot)
have come from the *allegedly* bacterial infected oncidium?
THANK YOU VERY MUCH IN ADVANCE!
sincerely
Tanya

p.s. sorry -- i guess polysporin CREME (not ointment i.e. water sol) would be
stupid to use on the leaf?

Tanya,

Considering the fact that it's an edge spot, I think you've done what you
can, and should simply wait and see. Judging by the pics, I think you have
little to worry about.
