Phalaenopsis keeps producing basal keikis

[Ray]

Question one: Is the crown of the "mother plant" intact? If not, that explains the keikies. However, while the production of basal kekies is not unusual, if that's all the plants do, it's certainly not normal.

It may be that you have a genetic odd-ball - the remnant of over-cloning, perhaps - but we cannot overlook culture.

You stated that you use RO water and don't fertilize. That is the best way I know to starve your plants. If you give the plant just a little food, it will go a long way to helping it bloom. It may not resolve the keiki situation, but if it blooms, who cares?

Don't misunderstand: fertilizer does not cause blooming, but starvation certainly can prevent it.
