Thin branches on my sps

[PhantomHalo]

Recently I’ve noticed my ASD Rainbow milli has started to grow thin branches. All other corals in the tank are growing normal. Anyone dealt with this before or know why it’s happening. It’s right at the collision point of my gyre from the back wall and the side of the tank. It’s also under a G5 Radion and a ReefBreeders 32” light. It’s sitting around 400 par right now. I just came down from a high PO4 and NO3 spike (around .3ppm and 10+) and it’s now .12ppm and NO3 is at .5. Thanks all!

How's the flow in this spot?

High flow. At the collision point between two gyres.

Flow issues are always a dilemma; try to fix it for one not unhappy coral and risk offending many more...

It’s been there for quite some time now and was growing normal. Now it’s just starting to grow differently. The only thing that changed was my increased nutrients, but none of the other corals are growing this way which is why I thought it was odd.
