I don't know if cperesc is still watching but I noticed Miracle Gro orchid fertilizer in the grocery store, Publix, today. Although I am not a fan of anything by Scott's, and am certainly not an expert by any means, it might be better than nothing.
My epsom salts come from Costco and I add the lavender oil myself; it feels and smells good in the bath and I always save a pitcher or two to share with the plants.
