I haven't watched the match, so all I will say is there is no difference in this respect between NFHS and NCAA rules. Wait until the fault occurs before the whistle is blown.

Occasionally you might whistle when a ball is hit into the net and someone makes an effort to play the ball, thinking it's going to be four hits, and then they don't touch the ball and you wind up a touch early with the whistle. I know I've done this.
