Confused

I have 4 plants that are all healthy..been growin over 2 months...weird thing tho i still have them on 19 hours of light but i can already tell the sex of the plants. Unfortunatly only one is female but it has white hairs growin on it and the other 3 have pollen pods on them im pretty sure..any idea why they are flowering even though i havent shortend the light cycle yet?

A plant will show its sex when it is vegged a long time .. Beware that they double in size when they are in flowering

stress??? autoflowering??? preflowers??

pre-flowers yo

aight thanks for the help
