Question about oddball plant

Hi there. I had a question about these plants I keep finding in my gardens.

I take my clones off the same mother plants. Not sure how to explain the different growth pattern other than a few from each run are retarded somehow. I am flowering a batch now and theres a few with that unique growth and odd leaves. Flowers are retarded too so im gonna eliminate them from the garden as soon as I see them now but Im curious why they do that.

I can't address your specific question...but I can tell you, by looking at your pictures, that they are all overfed. Only excess N produces that dark green coloration.

It also looks like one of your plant went into flower and back into veg? That could have been intentional or it could be your problem. Has your light schedule been changed or altered?

the single leaf is a hormonal expression usually triggered by stress .. Once the stress is gone from the plants life normal growth pattern's will resume .
