Good post, Push.
And Sativaforever knows what he's talking about.
A 1K HPS at the proper height will do little harm.
The same goes for morning, and evening sunlight.

At mid day, it is possible to to create tiny sunbleached dots with large water globs resting on the cystoliths and trichs.
This I have seen.

They are of little consequence.

So, mist if you must, just don't overdo when the RH is high.
And only at lights on.
Slowed evaporation invites mildew and mold, yah?

Aloha,
