3/4 look great, the fourth looks like a scraggly runt. Same conditions, so and nutrients. Right now, over watered and N, even though I haven’t watered in a few days. The soil getting cooler is changing the uptake for sure. Honestly, as poor as its performing, I wouldn’t bother running its clones.
Demi Moore is a great example of why you need to let her live and reach her full potential. You might need to make some adjustments to how you raise and care for her, but she might be the star of the bunch.
I would keep it if I had room. I’ve had a runt that was slow going at first. But it eventually caught up with the family. If I was running out of space I would give it away or get rid of it. You could always experiment with it.
The leafs look quite a bit different than the other 3 if i’m seeing correctly. Keep it and see what different phenotypical representation takes place!!
