I updated my site to a mobile friendly template last fall. I also started using K2 for content. Ever since then, my Adsense advertisements have not been relevant at all. I have followed all of Googles suggestions but nothing seems to help. Do you guys have any recommendations?

For instance, this page: how2instructions.com/how2articles/home_improvement/painting/how_to_paint_kitchen_cabinets.html
is showing a Nordic Track advertisement at the top and an ecommerce site at the bottom. I never had this problem before using K2 and switching to this template.

Hopefully someone can help me out, it would be much appreciated!

K2 will not affect your ads under your circumstances.
AdSense ads will be displayed according to your browsing history.
