I can't tell you what you should do, but I can surely tell you what I did.
Plants outdoors naturally get rain and wind and in someplces it comes often too.
I misted with plain water daily. I had compact CFLS andt he water hit them often with no consequences.
Also, after 4 weeks, I misted with 1/6 nute mix daily too. I did not mist with Nute Mix after Flowering started .
