Or should I only add the 1/4 tsp once, and when?
Normally, to guestimate 50 ppm, you add it at every other racking and at bottling. So, if you haven't added any recently (but you did when you stabilized, correct), then add it now. But if you added it recently, then it'll be fine until bottling day.
