To spray or not to spray

I have heard different opinons.
Should flowering plants be sprayed/misted?

...no way, mold will be an issue sooner or later, specifically indica's dense buds. Furthermore, you should never need to foliar spray unless you are try'n to save a plant from element deprivation or insects.
...NEVER foliar spray while the lights are on....the water drops act as a magnifying glass and will make burn spots on your leaves. Good luck.
