this is really odd... only one leaf

got some cuttings from a friend, and they seem to be doing ok (this is my first grow). But, there's one plant (i think its a burmese) that has only single-leaf branches, it's strange, and it's roots are not as well developed or thick as the rest of the plants. take a look:

i know there's going to be some variance in leaves but i didn't know 1 was an option.

also, do the rest look good to everyone? they were started in bubbleponics kit from cuttings 3.5 weeks ago

the one leaf happens often with clones, usualy grows out of it

I find that if I'm rougher with my clones that 3/1 leaf sets has happened
but like pilgram said, they would probably grow out of it given the right
conditions.

You can get that from a revegged or "monster cropped" plant too. It will grow out of it. just keep it healthy.

i'm a little new to this.... what is monster cropping?
