How regularly to feed orchids?

[Ray]

I try to look at nature as a guide.

In the wild, plants do not have a great deal of nutrition available, but it is mostly there constantly. Based upon that, I prefer to feed a relatively dilute solution at every watering.

Specifically, I use 125 ppm N. If you divide 10 by the %N on the label, the result is the teaspoons per gallon to use (divide 13 by the %N to get ml/L).
