He was aware that he possessed wind release, and also, it wasn't at any point in Konohamaru's instructions that he mentioned adding wind release to it. So yeah, he did add it unconsciously. Why would he go out of his way to add wind release to it, since he probably wasn't even aware that it's possible in the first place? He had trouble creating a full rasengan in the first place BECAUSE he added wind release.Since he wanted to impress Sasuke, he would've just made a normal full rasengan, but he didn't. He clearly had no idea what he was doing.
