Phenotypically different clone

My friend took a cutting from a cannabis plant in early flowering last march and grew it into a beastly man-bush of a plant and then flowered it to get some awesome herb. While the plant was flowering (maybe like 3rd or 4th week) he took a cutting of it so he could start the whole process again. The cutting rooted and started growing fine under 24/0 but now it's new leaves are messed up. They barely look like cannabis, the leaflets are round and independent, they are not part of actual leaves they are just round single leaflets sticking out of the growing tip of the plant. The most obvious answer is that the clone was taken too late in the flowering cycle but I don't understand how some normal leaves could grow on the cutting and then it's phenotype changes completely and it starts growing abnormally. Because it's a clone, it should have the same genotype and since it's under the same conditions as the mama it should express the same phenotype as well.... right? I don't think this could be due to telomere shortening as some people say it is because it's been less than a year since the original clone was taken (how long the previous grower had that plant is another story). Is it possible the previous grower had been taken clones of clones for a long time and my friend happened to get a clone that's like 10 generations away from the actual seed grown plant and that that is the cause of the mutation? He was planning on flowering that little baby (he only grows one plant at a time) and taking a clone of it just like how he was doing before. It's extremely sticky and crystaly (way more than you'd expect for a vegging clone) and it's really good genetics that he doesn't want to lose so the mutation is really bugging him.
Note: I'm also going to post this on the growery but since it has to do with plant genetics and mutation I figure a knowledge of cannabis isn't necessary for you folks to help me out. Also, no one seems to post there

It's phenotype hasn't changed. Genetically it is absolutely identicle as it's parents, whole plants don't just mutate like the infected in a zombie movie lol.
I've seen leaves similar to what your describing appear in extremely stressed plants. I've seen this with light leaks in dark periods, irregular lighting scheduals, pH issues ect.
If I was him I would check to make sure there are no light leaks, check the ph of his soil, make sure temp readings are normal. All the usual problem solving things.
In the meantime start another, just incase this one ends up being garbage.

well it's a clone, so it is identical to the mother plant... it has probably just taken a dislike to being reverted back to veg from flower...

If you created a cannabis strain that doesn´t looks like cannabis than you´re a genius (if you can reproduce it), because of obvious advantages that a cannabis plant that doesn´t looks like one has.
Like duckfoot for instance.

lol... it's a clone that is fucked from being taken from flower back to veg...
it should start to grow some normal leaves eventually.

Thing is, it grew some normal leaves after it rooted before it got all fucked up. And yeah it is phenotypically different. It's genotypically identical to the mother.

Its stressed. If you keep it in the vegetative state long enough, it will straighten out. This may take some time. How far into flowering was the mother plant? This may be the root of it all.
