All seeds have unique genetic codes and are like children, even though they have the same parents, all grow/develop differently.
Only clones grow identically.
My little Dwarf is just about to preflower-- I THINK lol. It popped out 10/3/23 so she's 1 month old, but I can see that 2 of your plants flowering before the other one, so perhaps mine is just late bloomer but she does SMELL. I was worried it may be a male?
