This is supposed to be an ORA Blue Voodo. It looks like hell.
What is strange is it was attempting to encrust where the part on the base is completely white. On the side that is not facing the light, you can see the flesh texture/pigment (although it is a washed out looking brown) or whatever it is called. On the side that is facing the light, the white areas don't have that flesh pigment.
The tubes that the polyps are in are growing strangely too. They are elongated, growing differently than when I received it.

I don't think it is pests. There are a couple other frags showing the exact same symptom - where the light is shining, the coral is white-ish, where the light is not focused, it is brown-ish.
Other corals show good/normal colors where the light is hitting and brown on the side the light is not hitting directly.

Not aefw.. I know what aefw look like.. Having had them in my last system and having them at the moment, I'm 95% sure it isn't aefw..
It looks exactly like light stress.. Now that I know what lights you use and your nutrient levels, I am convinced of this..
I am not saying your lights are bad- not at all- I'm just saying that I think the whites are a bit strong -especially for the low nutrients you have. Those LEDs are very good and should have no problem making your corals happy.. Under the right conditions and settings..
If I were you, I would reduce your whites to no more than 30%- maybe even 20 for the time being (you can ramp up slowly after you fix your nutrient issues)
I would also stop any phosphate absorbers or Carbon sources you may be using..
And get yourself more fish.
Personally, I think you need some measurable n and p to make your sps happy.

Thanks for the help.
Should I reduce my any other colors or just the white?
I just got 2 T5 fixtures as a supplement and went with ATI Blue Plus.
Should I not run them? Should I turn down blues on the Hydras because the T5s are blue? I was thinking that it would help give some diffused light during peak hours to avoid shadowing with the corals. I was going to run them for 5 hours.
Also, when you say stop any carbon source, do you mean carbon dosing or GAC?
Any advice is appreciated.

I'm really not an expert on LEDs.. I haven't personally used them for over a year but I think your probably fine for the rest- maybe reduce the blues to 75-80%..
The blue+ are pretty tried and true bulbs although with your LEDs and the blue + the tank is going to look dramatically blue..
You might consider changing one blue+ for a coral+ for more natural spectrum.. Coral + and blue + are a solid combination.
You may want to play with the led levels to get a look that you like.. But once you find a decent led mix, stop playing with them- it's just another parameter the corals have to continually adapt to.
I think the t5 are only beneficial.
You need to get your nutrients to measurable levels..I think that's pretty important.
Also, you may want to reduce your alk a bit- closer to 7.5, imo..

Is there any difference to the corals between coral plus and blue plus? Or is it just for the look we want?
