They are looking good.
Now, try this the next time and you will see a difference in growth.
At this stage of growth all autos are very close if you keep it simple.
But little things like understanding how looking and learning how root growth and making a root ball and training your roots. (Yes, I'm talking about uppotting autos) don't buy into you shouldn't uppot autos. Starting off in a smaller pot and if the roots take hold you'll see a little push in growth and stronger roots.
They are looking good.
Good luck.
