The first photo is my new baby, 17 days old. The second picture was my first baby at 17 days old. They are both supposed to be GDP auto. Is it me, or do they look like two different plants? The new one has much fatter leaves.

Like brothers and sisters, not all identical twins
Lookin good too
And Welcome
There’s an endless amount of variation from seed to seed. Regardless if it’s the same strain. Fem or not. Phenotypes.
@StonedCold13 thanks! I guess I’m just surprised at how much bigger she is than her sister was. Here’s her sister now.
Looks the same to me, one is just over all larger
Thanks all. They’re my first grows so it surprised me a bit.
No worries! Welcome to the forum.
Good lookin, healthy sisters IMHO. Doing good and welcome to the best canna site on the web.
My example is my Cindy strain one is almost 5ft the sister is 18 maybe 24 inches both full flower I always grow at least 2 of each strain it is amazing how different they can be Growmie
Heres a GDP comparison…
Same seed packet, same strain, 2 totally different looking plants as far as leaves.
Welcome. Looking good!
