This happened to me a couple weeks ago, got a little fuzzy thing growin on the foot of one of my cigars. Immediately took it out of the humidor, and put it in an empty cigar box. Came back a week or so later and ended up just chopping the end off with a cutter and then smoking it like usual and it was pretty good.
Smoke it, it'll be fine. What does your rh and temp read at?
There are as many opinions as there are cigar smokers, so my initial answer is to keep them at whatever the cigars smoke best for you. I happen to keep my between 63 and 65% humidity. Anything much more than that and the burn isn't as nice, and there can be draw issues among other things. Around 60 and lower, and they will burn too hot for my liking. I also try to keep my cigars a little cooler, but 70 degrees is ok. Around there and higher, any beetles larvae that are in there could hatch and you could have a beetle problem.
I was looking at some pictures on the net and to me it looked more like mold....also one site said that bloom forms crystals.....I have them isolated right now so I guess time will tell.
