Amnesia. Could it be this difference?

Hello everyone, this is the room of 13 plants.
8 of them are the smaller ones, not the high ones.
5 of them are those big ones.
Could it be both amnesia strain?

Im adding photos and video. The difference between their leaves (in size the most)
The highs, AND THOSE 5 (with bigger leaves), they got to me really stressed, and when i've flipped 12/12 they were allmost not eating... about 1L/day. Against those 8, they ate 2L - 2.5L/day.

Adding video for you to see the difference in head structure. And how it grows.
What is your opinion?
Could it be any other reasons?

Thank you,
Best regards

Well, it certainly is possible to get different phenotypes from the very same batch of seeds. It's more common with autoflower varieties, but still very possible with photoperiod strains.

I basically get different phenotypes with every strain I grow from every breeder.

Yeah it can get kind of annoying sometimes, like when you get a tall phenotype from an indica strain.
