I'm doubtful the Ashton is plume either. When you get plume it's not in one small spot on the cigar. I've heard of plants that were over fertilized ending up with conditions that will cause specs, even in an ash when it burns, but never a line like that. It looks like it's a raised area along a crease, so I'm tempted to think it came into contact with something.
Marccote, I understand why some of the brothers are questioning your legitimacy, not to rag on you, but I couldn't help but notice your spelling and grammar as an editor is a bit off center. I don't know if you've come here with an agenda or just to share and learn about a passion, but I'll tell you this. I don't consider myself a slouch when it comes to knowing cigars, but I am very careful about making declarative statements in here, because the knowledge and experience on this board can leave you humbled. I find it hard to point out something as simple as "No, that is quite obviously mold" because you've set yourself up as an expert with the fancy title. I hope you choose to lose the title and just be yourself around here, you would be surprised at whom some of our members are, but they don't flaunt it.
Now, a little jab, because we are all friends here and I want to be able to talk to you like any other brother, with a bit of fun and the understanding that it's fare to jab back with a kind heart.
Dude, your B&M is ripping you off, you posted fake Cubans and mold as plum. It's not positive advertising for your magazine at this point anyway.
Smoke a good one and I'd lower the temp from 70 if it were me, I like closer to 65 to prevent mold and beetles, with no ill effect on the cigars. I'd also check your humidity with a calibrated hygrometer, to make sure you are not above 70% but don't realize it.
