Mold usually destroys your buds.
What you could do is go thru each bud carefully and cut out the mold, then dry out your buds, clean that jar with javex, make sure there is no mold left on the buds then put them in.
I use something called Boveda Humidipak 8 gram, this prevents this from ever happening, it is a soft pack that you put inside the lid, it controls humidity up and down, it is a fool proof curing necessity. GOOGLE it, I buy mine here in Canada for .99 each and I get 12 at a time. You will never see mold on your buds again.
