Algae Growth

[eraml]

Have had my tank up around 2.5 months.
Recently added lighting (Kessil AP9X) around 2-3 weeks ago, and have had them on low intensity on a pre-programed Acclimation period - set for 30 days.

I have recently started seeing the pictured algae growth on the back wall - center overflow.
Any idea what type of algae this is and if I should be concerned?

I have a mix of live/dead rock in the tank - and am not seeing any major/large areas of algae growth on the rocks.

Really hard to see. Maybe retake picture under white lights?

Hopefully a couple better photos - taking today with the lights set more to white in the afternoon:
