Banana Sherbet XXL

Plants are strange things. All three of the banana sherbet came from the same batch of seeds. As you can see in the pictures the back left plant is stretching nicely through the trellis. The near left plant has grown somewhat but not mutch at all, and almost looks like a different strain. And as for the back right it's just a dwarf 😂it's hardly grown let alone filled the trellis. (ignore bottom right it's an og kush auto) all the plants have been treated exactly the same. No idea how it's happened! Any thoughts are welcome.
