I recently got my first air plant and noticed that there is some black gunk around the base of the leaves. It lives in an office and gets fluorescent lighting, I water it once a week by submerging it in tap water and letting it dry out completely on a paper towel. The container it's in gets plenty of air circulation.
I'm not sure if this black gunk is mold/rot, bugs, or fungus - does anybody know what this is? (Photos attached) Can Svlad the Tillandsia be saved?!
