I have been pondering this calcium thing for days now and besides getting feedback here and from other orchid forums I think my best option is to go with this as my fertilizer -

I'll continue using distilled water mixed with potassium nitrate to mist them however. If anyone sees a problem with what I plan to do please let me know as I would like to order this in the next day or so.
