germinated 8 BlackIceGelato seeds,7 popped wonderfully.
before those germinated, had a grape stomper seed and a runtz (undetermined variety) seed spring into life.
Impossible to tell from your video.
Can you please post at least one clear and close up picture of the affected area, and taken under normal light, for anyone to be able to answer this question reliably for you.
Thanks in advance, Organoman.
