Cut off the mold and throw it out, increase ventilation, this is a must or you will lose more. You could also remove all your buds and put them on a screen with spacing between each and a fan blowing at the screen. You have already been infected, you have to get out of dampness and get this dry, after hanging for a week they should almost be ready to jar. How are your plants drying, in a room, barn etc. Is there any air circulation ?
