Showing sex 3 weeks old...

I have a plant from some bagseed that was around 2-3 weeks old, and it already is showing female signs. It's got the two pistils, and it's only about 3" tall. It's very short and bushy, but I think it's unnaturally small. Is there any reason for this? Is it common?

This is my second grow, and I'm so damn confused with this plant...

some plants need to grow there roots firs especially females so it might take a little longer and if its from seed than i usually have a 2 week period after it roots that it stays the same just wait it out and see what bag did you get it from last 3 plants i did this way were unstable and Hermied out within 3 weeks of flowering

Make sure you aren't confusing the small spiky things(stipules) at the nodes for hairs. I doubt your plant is mature yet, and if it is that small I think it would be easy to confuse the two.

They grow depending on genetics and environment. I have some small plants going right now, some are in 24 hrs under 6500k, and some under 2700k in 12/12.

The ones under 12/12 are not as close to the lights as the ones in 24/0. So in 12/12 they are taller, but there are less inner nodes. The ones under 24/0 are shorter and bushier with more nodes.

Theres no way to know why its short for sure.

maybe it is an auto strain
