how are your nitrates, nitrites and phosphates? Any coral near by that would be stinging it? Notice any bugs on it? Have any chems in the water from gfo, carbon, etc? How long has it been since you changed water? Any addatives recently?

I'd get a nitrate/nirite/phosphate test kit asap. Any deaths in the tank recently? When did they start bleaching? The time frame may give you a clue as to if the water change is the problem. How often do u change carbon? Did u use different brands of carbon or salt? Or maybe a new batch? How much water did you change? The drastic change in alk over the past week may be the problem....

i brought up alk over two weeks from 6.8 to 8.4... i change 10 gallons every two weeks.. i use oceanic. no deaths ever... i change my carbon once a month.. i only noticed the bleaching last night... so not sure how long it has been going on.. i plan on getting a kit now!! never had problem before.. i plan on taking some water down to get tested on monday.. if i run phosgaurd without a reading, not running it now just curious, would this cause a problem or would it be safe till i know??

Change your carbon asap.. it may be leeching some stuff back into your tank if its run too long or if you weren't running enough and it stopped pulling out organics. Phosguard could do the same thing so be sure to change it as specified by the manufacturer.
Not sure if others would agree but whenever i think to have a higher alk, i would add it to the replacement water before adding the water to the tank (if you were attempting to match your current tank alk to the replacement water alk). The shift in alk between your old water and new water may cause some problems.
I didnt see anything nearby that could be causing coral warfare in your tank. Its strange to me that it's going from the bottom up. Do they have enough flow over them? can you see the polyps swaying in the water?
Have you added any new inverts?

also be sure to take a pic everyday to make sure its not spreading or notice how it is spreading. It kind of looks like the bleaching follows the shape of the rocks.. they may not be getting enough flow to the lower portion of the corals...
If you get it taken care of soon, there is a good chance for a full recovery of the corals.. i had some issues a while back and most of mine have come back.

Looks to me like its possibly RTN/STN ( Rapid or Sudden Tissue Necrosis)   If it is, even if you can figure out what the cause is it may be too late to do anything. Google it for plenty of info about it.
 
  If those colonies continue to rapidly lose tissue, it could wipe them all out within hours.......    Be prepared to try and frag some of the healthy parts of the coral in order to save them.
 
 Sorry for the bad news and I hope I am wrong.    Also, 1.022 salinity is kind of low for SPS, what are you using to measure salinity ?   Not saying that is the cause but double check your salinity with a Refractometer if possible, it could be more off than you think.
 
Good luck

Just out  of curiosity before this started did you move any of your power heads ? As reef'd mentioned all the loss seems to be on 1 side .  Are you adding chemicals to the display or sump and is your return pointed at these corals? Dosing all at 1 time or are dripping it in ?Also how long have you been at .022? Are you toppimg off with R/O ? And are you dosing to feed your corals and what is the date on what you dose if you are?
