Any tips on how to get a phal. to flower?

Fertilizers do not trigger plants to bloom. They have to be at the right stage to do so.

Do they look healthy? How do the leaves look? How many? If all is well, thjey should make flower spikes in the fall and you will know what colors they are in the spring time when they flower.

If they are not in good condition, then they might skip a season.

As Silken mentioned, temperature drop and sufficient light are the keys.
