One approach would be to duplicate the layer
Gaussian blur the new layer heavily
Create the mask and brush it in with an opacity of 20%
The Gaussian blur will likely make the mask very smooth, so add some noise to it.
Or you could do something similar.
Duplicate the layer,
Gaussian blue the background layer
Use the lighten blend mode on the duplicated layer to bring back the details, then erase the defects bringing the Gaussian blurred layer through.
The trick with masks is to go easy on the brush opacity. 100% can be rather coarse and does not provide a smooth transition. Also, you can Alt+left mouse click the mask to work specifically on it. This is great as it allows you to blur the entire mask that you are applying.
The problem with the clone tools is that is rather abrupt. If you want to use it, do it early in the routine or at least before noise reduction. Sometimes its easier to correct combined sub before the colour combine routine. A query however, how many green subs did you take? This should have ultimately been removed with the combine function as it would be classified as outlier pixels.
