Acros Plating

[Markxc]

Does it mean anything that these acros stopped encrusting downward and have started plating sideways/curled up? Not sure if I'm describing this correctly but you can see it in the pics. Im not too worried about it cause they're growing but am wondering if it means something like not enough light?

Hello,
I believe that this is purely light optimisation... it will grow in a way to capture more light possible.
I don’t see any issue.
Of course, flow should be also include in this equation!
Cheers

I've had it happen in response to very high flow.
