It could already be too late, or you might be lucky. It is too humid in your drying area. Definitely follow advice above on fans/air-movement. I'm asuming you don't have a dehuey or it would already be on? If so, start by slightly warming the closet with a space heater, but only to 65deg if possible. The heater will dry the air. Normally this would be a bad approach, but your case is different right now. Have jars ready so when it starts drying suddenly you can keep it from turning to straw/dust before the cure.
Grab a hygrometer (humidity scanner), they're like $10 at chain stores. Once you know the relative humidity % (rh), then search here for best drying/curing practices. Also get a 60x or better magnifier and learn what mold looks like, plus uv/backlight will make it glow ($5 bulb, or get the magnifier with money-checking led).
If buds are moldy, please don't risk your health or anyone else's, and hard as it is, just use the experience for next run. If you take advice from the harvest threads you can't go wrong.
