Add a Channel Mixer layer, and go to "Output channel: Blue". Change it from 0/0/+100/0 to 0/+90/0/0 (make sure you get those numbers in exactly the right order). Mask it to the area.
Then add a new blank layer above that, and choose your Clone Tool. Make sure it's set to "Sample: Current & Below" in the options bar. Then do your best to carefully clone the rest of the issues.
