I posted a message about a month ago about fertilizer because my phals haven't bloomed in several years. The sugestions were more about light, but it seems they are getting plenty of light in a large East facing window.
Well I decided to change the fertilizer anyway from a 19-31-17 fertilizer to a 30-10-10. Both are recommended for orchids. Anyhoo,.. Now ALL 4 of my phals are sprouting a new leaf each. I'm happy they are healthy, I wish they were spiking instead though.
