Fertilizing Phalaenopsis

[camille1585]

I use 125ppm N of whatever fertilizer I happen to be using, at every single watering (I flush out the pots once a month too). The orchids bloom and grow very well. 125ppm N works just fine for all my orchids (except the masdie which gets much less(90) and the cyms which gets a bit more (150)

Keep in mind that 250ppm N is for commercial growers in their optimized growing conditions. Everything they do is to have super fast growth, and the plants need more food. We need a few years to get a seedling phal to bloom. The factory growers only need a bit over a year. Also, you don't know the frequency of the application. In the past, it was thought best to fertilize strongly and rarely (like once a month) but it seems that now, weakly weekly is better.
