no, actually they're not too close together, and they each get watered
with fresh water (pots are put on the dish drainer tray and watered
thru, and they sit for a few mins, then get put in the sink to drain
out, about 4 pots at a time. water from drain tray is dumped between
pot sets. maybe no more of that sitting in communal water, even for
such a short time.....)

i'm assuming what's happening is that something is becoming airborne
and lands in another pot. so far it's only been three, but i'm worried
it might spread, which is why i was looking for a preventative spray or
something....

two other plants (both from the same nursery... hmm...) have something
*else*. looks like white chalky stuff. i've got this little
collection of plants on a table in the corner, in quarantine.... :-)
