You might try moving the blue tipped up in your tank, just to see if getting more of the same light makes the difference....or lowering your lights over the tank if thats possible.

They are the highest & my lights are just 6in above the tank.

My parameters are good. I try keep the alk steady. Going to fire up my calcium reactor soon. I add small amounts of gfo. I nuked some before from a to much of a drop.

I'm amazed your colours are good. You have very little in the whiter spectrum and heavy blues. Are the blue + not lower in par than the coral + or the new aqua blue specials? Perhaps I should switch them our for a similar combo to yours. I have all those bulbs.
