Sorry to see such a beauty on full mold..
Next time you do outdoor you HAVE to always immediately remove moldy spots.
Mold is a result of fungus and fungi spread via spores. This means you want to remove anything that can spread out spores asap.
The guy who told you to leave it on obviously doesn't know much about outdoor growing.
If you do not want to remove much whatsoever, you have to spray hydrogen peroxide (food grade) 3-8%, combined with clean tap or osmosis water (depending on your location).
You should NOT smoke a plant that has got mold all over it. Very dangerous because on this stage the spores most likely spread to the healthy parts aswell.
Furthermore, you can kill of the spores of mold with a hydrogen peroxide water mix aswell (research "Bud washing") but it won't affect the toxines that already spread into your plant.
Thats why you want to remove moldy spots ASAP after spotting.
