Bob,
OK, just keep that up and hopefully the plant will simply grow out of it. If it continues to worsen and you're afraid the plant will die...you may need to transplant into a mild starter soil. Some plants and strains can handle that rich soil and others can't. And also I've heard that the soil itself is not totally consistent from batch to batch and you may have gotten a strong batch. You should be able to get by with no nutes for at least a few month.
Make sure to allow plant to dry between waterings and that the other grow parameters are up to snuff...humidity, heat, ventilation etc.
Good luck,
JD
