Different Size Plant Same Seed?

I ordered 10 White Widow regular seeds from an online seed bank. I managed to get 7 out of 10 seeds to be female. (Lucky I know). Now 4 out of the 7 plants are shorter by a foot or more and have significant signs of budding and multiple site, while the other 3 are super tall almost hitting the roof of a 7 foot tent and are just starting to show bud sites with hairs. Why is that? All were grown exactly the same , nutes lights soil etc.

Phenotypes they can have more indica or sativa in it.

x2 different phenotypes. You even get different finishing times.

WW -Indica 60% Sativa 40% but that all varies to some degree, they try to breed it out, but that phenotype (Growing Tall) surfaces now and then.
Geno-type. Right in the heredity of the plant.

IMO- get some "Bush Master" Humbolt makes it. it stops your plant from stretching alot.
You don't need much just a dose or two. I use it on all my plants, for about 3 years now. the stuff works good.

Good luck on Your Grow.

Thank you for the responses guys. The big ones aren't only tall they are monsters all around
