Raid6 wasn't completed until Linux 3.19 and I wouldn't call it stable yet.

https://btrfs.wiki.kernel.org/index.php/RAID56

I suggest you upgrade from Wheezy to Jessie and install the lastest
backports kernel and latest btrfs-progs from Git (there's no
stable-bpo for btrfs-tools) if you want to use raid56.
