Its the size of a red hair, its actually on the red hair can can be flicked off with your nail.
Also its not penetrated inside any nodule, its just kind of outside the nodules random bits...
It does look attached to sacks and developing leafs.
Under a scope it looks like criss crossed lines that intersect.
Its very small and can be removed with a finger nail (That is when you can even find it) You have to look to find it, breaking buds apart.
100% NO damaged plant matter, it all looks great.
There is NO "Rot" what so ever. Just flick it and its gone pretty much.
Also This is my first grow and I have never looked inside a bud ever till this week.
I have to mention, when I got my 215 I was diagnosed with a solid case of OCD but I really do see the fibers.
When I removed one it kind of squeaked like a web being removed and I had to neem my buds with a pretty good infestation of mites but I dont have any mites to look under a scope to compare.
