What's the best fertilizer(s) for Denphals?
 

I just built an orchidarium for my vandas, dendorbium phalaenopsis, and cattleyas. It may be a piece of cake here in the hot and humid tropics (Philippines) to grow orchids but I'm fairly new and would like to know what are the best fertilizers for denphals? So far, I've mastered the "art" of caring for my vandas ( I use Gaviota bloom booster and balancer alternately each week) and they have always rewarded me with spectacular blooms like no other) but on denphals in pots, would a high nitrogen be advisable while alternating with bloom booster or would a balance fertilizer be sufficient enough? Thanks...
