What do I do about mold?!?!

Hey,
This is my second time growing, first time just did two plants outdoors, turned out ok. This season i decided to not mess around and go a little bigger and pay more attention to my babies. Got 5 plants, everythings been going smooth up till a few days ago. I noticed some mold on one of my buds and im close to harvesting by the end of this month. I researched alittle but mostly only found that you should tear out the whole plant so that it doesnt spread. Is there anything else i can do to salvage the plant or treat mold cause just a small bud has some on it. any advice welcome!!!
please help fellow stoners!!!

i had a small mold case starting on my girls last week, i searched around and I found a suggestion of one tablespoon of baking soda per gallon of water, foliar spray. I did this yesterday but i couldn't tell you if it has worked or not yet. The article said 2-10 days before you were able to tell.

Make hash!

if your bud is rotting take out infected areas
i dont know what you would spray i spray nothing
that bud rot spread fast,so do it asap.
do not touch or sqeezes yor bud

Thanx everyone for the helpful info. I cut all the mold off yesterday sorry no pics had to get rid of that shit fast. only had to sacrifice about 5g of bud. cleared out a tree so there getting more light so hopefully that will do the trick.
