My first instinct is to wonder if the roots are getting too much water, but it seems you have the right soil. Check to see whether it's getting too much heat, too much cold or a draft, like from a heater vent. You may want to try to propagate the plants, just in case they are going down for good. This article explains the serious stuff, like root rot and fungal diseases.
