Change you schedule to less than 12 hours light, 11 would prob do it but in this case try 10 for a couple of days see if that triggers full flower.
Its trying for sure, once in full flower you can work it back up to 12.
Shocking it with 24 hours lights out might well work, does not seem needed yet.
