I have this too on most of my trees and have also thought it is DL / Neutrog that I now use.
What I have noticed is that it more prevalent on Our non organic substrates, eg Diatomite, Kanuma, as I have rarely seen it on the pots still with Rays mix. ( maybe it is just 'cos it black any way?).
Like yo I just sprinkle DL or Neutrog on the surface of each pot.
Took some photos today to show you.
I always thought it was moss starting to grow that never developed properly and thus went gooey. I have just scraped it off as it will clog up the top of the soil
I notice it is more prevalent on my trees that are shaded or not in full sun thru the day

As too your further posts. I have found this green on akadama Kumra and maybe a couple of other full in organics. Like I siad I would not be worried if the tree was growing fine. The JBP seedling I have noticed this most on, maybe need not be watered so much but as it is powering It hasn't concerned me. Won't need repotting I should put it to the side to dry out for a while and see what happens come spring. I plan on more pine seedlings in Akadama that has given me the best esults with it so far.
That said I would rather it not be there just for the look of it even. I have seen how well spag moss wipes away fungus from anything it touches but then again I maybe have seen it go green on the surface of a pot. But I would try 15% decomposed spag moss(bargian

) and maybe limit the water a little come spring to see if you can get rid of it?
Have you tried growing moss on it. They have said that if moss is happy on a juniper you are watering it too much. maybe diatomite has changed that

It's too bad your in such a hurry cause the stories I could tell you, Bushels and baskets of stories, hole crates full of stories. But if you can spare a moment I will tell you one story.
