Moth orchids Phalaenopsis ought not be watered from above. water will pool in the base and rot, hence the leaves fall off.
Watering Phalaenopsis needs to be done only when the roots in the pot are turning silvery. Lift the inner pot out of the cover and look at the roots. If they are green do not water, if they are silvery plunge the pot into rainwater for about ten minutes and then let it drain.
If water does run into the base of the leaf, dry it with a bit of tissue etc.
