Help!! Red planet and strawberry shortcake - strange growth

My red planet and strawberry shortcake are growing strangely. The strawberry shortcake continues to encrust, but does not grow upward. Plus it has these very spindly fingers that are growing horizontally or downward. Red planet is doing the same thing. In the pic with the strawberry shortcake, my pink lemonade next to it is doing just fine. Any thoughts on what could be causing this.

The red planet is low in the tank - and not a high flow area. But I had it in another location a few months ago. I'm not sure if it was high flow. But I also have a green planet that is in a high flow area and its doing the same thing.

The strawberry shortcake is so close to the pink lemonade though, that I wouldn't think there would be a huge difference in flow, and the pink lemonade is not doing that.

As for tabling, what I thought strange is that the tiny fingers are actually pointing downward. ????

 

I'm running the Aquatic Life hybrid - 4 Blue+ T5 bulbs, and 2 Kessil 360s. A couple months ago, after I took PAR readings, I mapped them on a photo of my tank.

 

Thanks for the replies
