ok, first off try your best to get a more in focus pic, that would help a ton, and are the green samples on the left wet? and the darker ones dry? if they arein the same stage of drying and the same strain you def got somethin not good goin on there, unless the nugs on the right were simply just purp.
2nd. def dont throw it away, worst case scenario make hash n do an alcohol wash or butane extraction then cook with said hash. medibles are better than nothing.
you can see the mold generally IME.
and also in my experience buds do darken after drying, they dont stay the same lime green color, at least not always, i do believe this is the chlorophyll leaving your buds, which is what u want.
and also i hang dry for a week or two before i even start the burping process
thats cutting it way too close
