Frogspawn Randomly Retracted found slight discoloration

[MultipleTankSyndrome]

I recently had to move my frogspawn around a lot due to a rescape and weekly maintenance, but it open right back up just fine.
Earlier this morning it was looking like all was well and then I run to the store to come back finding it COMPLETELY retracted. 

I turned off the powerhead and its slowly creeping back out but I found a brown spot at the base in between some heads that looks out of place.

Is that brown spot something to worry about? BJD? or am I just being a paranoid new reefer? 😛

 

I checked my parameters and everything is looks good so I am at a loss.

 

Any advice or info is greatly appreciated

I wouldn't worry about that.

Sounds normal to me. Corals can close up at times for no reason.
