Ufortunately I can't see the picture and am not a breeder but have grown for a long time
Trichomes on a seedling less than a week old.
Maybe I have something new to learn because I just can't really is it happening BUT I could be wrong
Not sure if we can call them 'trichomes'. I can confirm they arent plant hairs or anything. Ive never seen a seedling do this within a week, I have seen this with some strains/clones that exhibit these premature trichs later in veg though, without being flipped into flowering. These were not AF strains either. Hope this helps.
