mushy psuedobulbs on a miltonia
 

I was inspecting my orchids this morning and found a recently transplanted
milt to have 2 brown and mushy psuedobulbs that came apart when handled- I
unpotted it expecting more damage, but found 1 new growth, 2 bulbs, & 1
recent growth that dropped off. roots all looked white and no rot. bark and
moss moist but not wet. 10 ft away I have a Sharry Baby seedling that has a
yellowed new growth. Weather is changing, heaters are now on and off
depending on the weather

What caused this? I sprayed the roots and pot with physan/water before
repotting and will let it rest for a few weeks.

I noticed in my growing area a white film on a humidity tray and a beta fish
bowl....he got new water too! I hope it was just plaster dust.We have been
remodeling and stirring up mold spores is not unlikely. I think I read that
a certain type of orchid does not like physan, but I cant remember which
one- I'll spray the whole collection. Can't wait to move them back into my
new plant room wher there is less of a draft- that may be the culprit
