To how you should act now i agree with AsNoriu.
Even tho this mold is not that aggressive, if you have it at one place your plant is abviously in good conditions to get it again, especially when theres such mold just on the plant. Chop it and take what you got. Next time you could use a fan, thats seriously run 24/7. Like you can see on the locations. This type grows in buds, where circulation is bad, light cant reach and humitidy is high.
Good luck and sorry for you
