I wouldn't call it "extreme" but it is definitely there on the moss. Nothing on the roots or orchid itself.

I don't feed that often, usually weakly weekly in warmer weather or whatever is appropriate for the orchid itself - currently in cold winter, weakly biweekly or so, since I have plenty of active growth under my LEDs. I also use KelpMax once a month.
