There are a lot of cloning methods on YouTube, not being sarcastic. I've come to find that it's very important to sterilize your scissors or whatever you use
Those clones taken in flower do have odd growth. There's a term for this but I don't remember. A clone is an identical representation of the mother so it will have the same growth. Did you reveg your clone or what?
With feminized you know you'll get a girl but you don't know about the phenotype. With regs you could get 3 girls.... You could also get none. Sounds like you're only going to grow one plant so go with the fem, because stone cold said so
