Darkdevil Autoflowers

Is this normal for two of the same plants in same conditions to be so different? One of my girls is about a foot tall and making decent flowers and the other is almost 2 ft tall with tiny flowers. The tall one was the runtil for awhile. They both are 6 weeks old. Are they about where they should be or behind? Thanks for any help

Looks like the one on the right is stretching to get light.

are they the same strain?....the runt looks like it will be tasty

Yes they are the same but the runt is the tall one. Lol it took off like crazy at about 3 weeks and the short one just got fatter.

The lights are kept like 2 inches above them at all times. I move when ever needed.

The distance between nodes on the tall one is indicative of stretching for light. Other than that, chalk it up to mother nature.
