Is this a balk?

In a game I was doing today, the pitcher would put his hands together while off the rubber, separate them, then step on the rubber and go into his stretch, set and delivery. When he put his hands together while off the rubber there was clearly no intent to decieve any runners, and nobody was decieved. My guess is that he was either adjusting the ball or it was simply a ritual before he actually stepped on the rubber. I'm still not sure whether this should have been called a balk due to the pitcher making a motion associated with his pitch while off the rubber, but I didn't call a balk.
