Too me it looks like you might have too much flow across the top BUT not enough flow through the branches of the birdsnest. From my experience, if the isn't enough flow through the branches, the tissue inside the colony dies off. This die off causes cyano in the lower part of the colony. The colony then goes up like a lit match from the inside out. Is the colony near a power head that the top of it is getting blasted?
Try switching your flow around so that you get rid of dead spots in your tank and get flow through the lower part of your colonies. To me this is a flow problem, not nutrients.
