I have trouble coloring up pinks!!

I really hope I have enough light... I've got a 24" tank and an ati led power module with 4 bulbs directly over my rock structure.

Is 24" back to front? If so, an 8-tube power module would be my choice. However, 4 bulbs may be OK providing that your corals are direct underneath the bulbs.

My tank is 21" (back to front). I use a 8 X 39W powermodule.

Its 30" back to front.
I have LPs that are thriving on the edges on the sandbed
 
In this case, light could be the main issue. If I had a tank with 30" depth (back to front), I would run a 10-tube power module for an sps dominated/only tank. This would ensure proper light coverage across the tank.
 
IMO that light is alright for a mixed tank with some care taken as to SPS coral placement.

The LED clusters on the ATI units dont use lens, rather they use tiny reflectors and I can confirm from my own PAR measurements that the spread of light is pretty good...hence I would place this 4xT5 with 3xLED cluster unit more like an 8tube T5 unit.

An 8 tube unit will be far better for coverage for sure...but I wouldnt be concerned about a lack of PAR since this sounds like a mixed tank.

IME most of SPS colour issues is down to water quality rather than light out put or light coverage...

4 led clusters not 3.

All of the sps are directly under the unit. Here's a picture when it was first installed

Sahin are you sure I wouldn't be better off selling this unit and going with an 8 bulb sun power with two blue reefbrite tech LEDs on each side?

I'll sell this light right now for 1600 bucks lol. 4 months old too haha. I don't really use the programming. I'm just a little upset I didn't pay the extra 300 for the 8 bulb. I don't want to go out and buy a 4 bulb sunpower to add to it

I would rather keep the power module if it'll work for sure
 
What type of carbon are you using and how much? Since your tank is still breaking in I think that's part of you problem. Your nitrates imo are low. I think I would feed more,pull the socks, ditch the gfo and carbon for a while. Keep an eye on your parameters and let your nitrate build up a bit. I think Sahin is right that your lights are not your problem.
 
Tons of skimate... Gotta change it twice a week. 8" skimmer cup. I just added gfo last night for the first time on this tank.
I use lignite carbon
 
Ok so no camera....

UPDATE
Ok so that brown mili is still brown but get this.. It has full polyp ext and is encrusting!! What gives!! I'm changing my salt to red sea to see if that changes anything

I doubt it's the salt at all. IME, some millepora take a long time for the polyps to color up, even though the coral tissue is brightly colored.
 
I would try moving it up closer to the light, or increasing your lighting time or intensity. Everything else seems to be in line.
