diffrent growth help

hi guys and girls,im growing 3 fem northern lights from nirvana. they have all been put in the same conditions but i plant is about 6inches tall, ones about 2 inches and ones still tiny just 4 little leaves. why is this happening. i have tried to swap the pot positions but 1 plant is just growin mad and the others are still growing realy slow. they are in the same soil, have same size pots and same amount of water. whats going on?

Not all plants grow the same.

i assumed that the same seeds in same conditions would be quite simular, theres hell of a difference between these 3. im limited on space so i will have to flower two smaller than hoped unless they catch up now.

This is often caused by phenotypes when not caused by conditions. They are genetic distinctions between the offspring based on genetic combinations of the parents.

right over the top of my head

Try to post some pics so we can see how they look. Keep in mind that males often grow faster than females.

they r all feminised seeds. i will try and get pics up but i dont know how to do it

Feminized doesn't necessarily mean anything. Males still sprout, there are just supposed to be fewer.

Yep, phenotypes will cause many differences, but that isn't the case, I suspect. The differences are too great, at this point in their life, for it to be caused by phenos. Okay,...how about some info, or pics? Lights? How far from plants? What medium are you using? What size pot, if any? Any nutes yet? Temps? Humidity? Etc....?
