Mornin' megatron.
The pic of the deformity on the small leaves looks like nothing more than physical damage.
I see that on that clone, you have exposed the hollow core of the main stem- get that sealed up right away. It's very dangerous to expose to the possibility of disease.
I also see signs that your plant would like some more light or less water.
And it's too deep in its pot. Cut the rim down to no more than an inch above the soil surface.
There's some weird wrinkling going on; please tell us about your soil- type and pH.
