Let me offer some different thoughts. Please dont take this as criticism, more less perhaps an error on my part, but never personal until I have to be ;)
I would say that plant hit a period of stunted growth at some point. The fact that there are brand new white pistils next to old weathered red pistils show an abnormal growth pattern. If I were to guess id say that the bud was starting to finish then was either reveged or had ran out of feed. I mean sure the light could be too high causing new growth to explode out of that area, but im pretty sure thats all that is is new growth coming out of the path of least resistance, meaning where the oils are not hardened over.
Id like to know the medium, feed rates, veg time and current flower time. Some overall pics from a distance to see the entire plant, and a pic of the top with the lights near off, or right when they come off or go on, use phone light or something to get a better shot of whats on top. I doubt its mold, im guessing just a bunch of new pistils coming out.
What was your humidity levels and what kind of light are you using and how far from the plant is it, and at what lux/par.
Im thinking some of that is just flash or reflection.
