is this mold??? how?

Walked by my carboys as they're oaking and saw weird stuff on the top.



I added oak to it on 12/28. prior to this everything was spot on for pH, TA, SO2 levels. One of the jugs (out of 3) had a white film on top with little yeast looking logs. I assumed that to be the MLF bacteria. Now that one and another have this green spotty stuff, while the third doesn't. I used starsan over the oak spirals as well before adding them in. help!

I am NOT the expert, but looks like "flowers of wine" (mycoderma) to me.

ok. i made and bulked aged for a year, all the apple was made together, racked from same ferment, bunged and airlocks filled at the same time and from same k-meta solution, went in to check airlocks levels and 1 out of 4 had this, why? and what to do to never have it again,
please any advice needed and wanted to have this never happen again, level lowered for pic's then topped back off,
