If your maintenance is 2400, 2100 on non-workout days + 2400 on workout days is an average deficit of 180 calories. You can't do SS on a caloric deficit. Can't be done (unless you have a lot of fat mass to burn to make up the difference). Go for recomp at the same BW (thus my recommendation of 2100 and 2800 or 2k and 3k as John suggests).
Also, the weight jumps programmed in SS are based on overfeeding. Start deliberately lighter and add weight deliberately more slowly if you are going for recomp. Your first week of workouts should be frustratingly easy.
