Look, please. with Question.

Oh,, this seedling, she is 5 months under veg. I never seen this before it just looks to me like it's flowering, or are there strains that just looks that hairy in veg

p.s. shes been cut out for clones before and most probable root bound, because i'm that cruel to keep in a small pot. just in case your need that to answer my question.

looks like you have pre-flowers which isn't much of a suprise if it been vegging for 5 months

The pics doesn't show them very well, but they look like hairs to me. Judging by the color at the tip they have been there a while. Anyway, they are preflowers. Totally normal, and mostly you'll just see one or two (up to 4) at a node. It's a female. Showing pre-flowers can be strain dependent. I've had some that never show till 12/12, some that show pre-flowers before alternating nodes (maturity). Kinda nice when they do because sexing becomes easier. Per-flowers are when I tend to notice the odor start to go up as well.
