Sounds like a perfectly sensible approach to me.

For the benefit of other members reading this thread, I think little real harm would ever come to an orchid from fertilizing except maybe if someone is using an extremely high concentration and getting leaf or root burn.

This reminded me of something I was going to add before but forgot: We aren't necessarily harming or starving our orchids if we do not fertilize. Unless we're growing in an inorganic medium and using only distilled water, some nutrients and minerals will get to the plant somehow and most of the mixes we use have bark, sphag, or other organic material. One shouldn't feel like they're neglecting their orchids if they dont' fertilize.
