Can keiki paste start new crown growth after prolonged setback
 

I have a NOID mini-phalaenopsis which went 20 months with no new leaves or flower spike. It did grow aerial roots. I applied keiki paste to a node on an old flower spike and to the crown, just to see if it would help. About four weeks later, almost simultaneously, I got new growth at the node and the beginning of a new leaf at the crown. The new flower spike didn't make it, but the new leaf continued to grow. Was this coincidence, did the keiki paste "jumpstart" new growth, or did it actually trigger a keiki from the crown?
