yes now with the second frost you must pay extremely close attention for mold. especially since you say some warmer weather is coming. read, read, READ on prevention and treatment. if you think you have to harvest early, make sure you smoke only buds with no mold. i wouldn't risk the harmful side effects of moldy-pot-smoking. prevent if you can afford it. let me see if i can find any info on it...
this gives a little info and some tips for treating/removing, but i wouldn't try the mouthwash thing.
