Almost all pitches can be thrown with a variety of speeds. It takes some trial and error but a basic rule of thumb is, the more "skin" on the ball will slow it down. The simple way is more fingers or finger parts on the ball, or placing the ball deeper into the palm of the hand.
Remember the off-speed is not a change up. Off-speeds should be basically -1 to -10 mph from your fastest pitch.
I learned this from Doug Gillis. Hold the ball deeper in your palm and move your thumb closer to your index finger. Everything else in the mechanics stays the same.

Which pitch? Drop?
