Please DON'T do the ice cube thing. It is one of the worst things you can do to any orchid. Orchids are tropical plants and the ice can do damage if not eventually kill the plant. Mix your fert. with room temperature water using less fert than directed. I would hold off using any type of fert until the plant has established itself in its new medium. Water about once a week until the water runs out the bottom. Make sure you don't let your orchid sit in water.
