Ya, I have these little 1 leaf spiral things on my plant as well. Honestly I messed up my fim/top on this plant only. I cut it a little short, more like a Top than a Fim, so at first it looked stunted and out of 1 side grew a little stem and some wierd top that wasn't like a new branch type leaf, it was more like just a tiny baby leaf that had opened but was trimmed near the nub on the leaf, with barely any actual leaf, it was just a circle of 5 little stems bunched together with tiny leaf material at the end of each one like it would make 1 regular mature leaf if it was on 1 stem, but the leaf material all stunted.
What I think happened is the hormones that would regularly tell the flower to grow out on both sides and then open up into 5 leaves got mixed up and told the little flower tissue left on the one side of the Top/Fim to grow out as if opening like the flower hadn't been topped/fimmed. Then it tried to open with 5 leaves but it had been cut so it didn't have tips. Basically I cut the Fim/Top too short but left some tissue on 1 side. Now the plant is confused and growing the lower leaves weird, with 1 of the leaves from the 5 leaf sets spiraling out.
Anyway, the other part of the main stem cola where I topped my plant trying to Fim it, started to pop 2 more flowers to grow new stems or colas to possibly give me a 4 colas plant, but the smaller forming leaves lower on the plant are doing the 1 leaf spiral deal. I clipped the weird stem growing out of the main stem from the Fim/Top, and I'll see whats going on now. I'm 21 days in from when the seedling first broke the surface.
If I remember I'll come post an update and tell you if the plant straightened out, taking away some of the stress.
I hope you understand what I mean lol
