Comment on Applied Physics: I have a problem with my wind wheel.

I don’t believe that the reason for this is density changes of the wood but more likely imprecise dimensions. I can’t really tell from the picture, but the lower blade seems slightly larger or maybe even thicker.
For example, the section marked in green at the heavy blade seems to be bigger than the blue marked section of the light blade. So I would suggest sand paper.
