Ok, give this a go:
First, add a Channel Mixer layer, go to the Blue channel, and set it to 0, +91, 0, 0.
Then add a Levels layer, and clip it to the Channel Mixer layer. Enter these values:
Red 49/1.00/255
Green 64/1.00/255
Blue 56/1.00/255
At this point the whole photo will be an odd colour. So return to the Channel Mixer layer and invert its mask to hide it. Then carefully paint it on to the glare area.
