Hello,
I have some phal seedlings that are getting some horrible spotting on them.
I've had them for over a year now. They've been in the same place in my chid hotel that whole time. Out of direct sun of course.
A couple of weeks ago I noticed changes coming. These spots started.
I've separated them. Treated them with Physan.
I don't know what Caused this?
Nor how to stop it?
Or what it's called?
