no.
"good" mold will not eat it or neutralize it. you'll just have more mold on your plant contaminating smoke and edibles, lol.
there are no effective products against fungus. And the ones that are partially effective is nothing you want to spray on flower. Even the products a commercial farmer has access to. Also, anything "organic" thatt's effective at killing life is probably not safe, either. "Organic" doesn't mean shit relative to any meaningful causality.
cut it out, throw it out. Even then, it's likely spread. Your eyes are absolutely not good enough to assess if it is infected. it was already spreading spores all over the fucking place, so ... unles you lie to yourself, you will be smoking at least some spores or fungus.
