Looks good to me, Chris. Just keep an eye out for the hard water deposits appearing on the leaves again.
Another thing you can do to refresh your orchids is carry them outside if there's a good rain predicted, so they get a rinse with rain water. I know that's probably a pain, but the rain water is a great thing, and about as pure as you can get without rinsing with distilled. Then be sure to let them dry out for a day or two before watering again! The drying out part is ever more important as the temperatures increase and there's more chance of fungal diseases.
You're the only person I've ever heard worrying about orchids getting enough calcium.
