Growing funny not sure what to do

I have 4 auto ak47 but one is coming up very different. Is it just a mix up from the seeds I got or am I doing something wrong. They are grown out side using 3 part cultivation nation.

This one is extremely different then the rest but all supposed to be the same seed

I don’t think you are doing anything wrong. They look healthy enough. Sometimes they just do what they do. It is a hybrid. They breed them to have specific tendencies. I would prune a few of the big fan leaves at the top. Maybe 3 or 4. If they are shading bud sites those would go first.
