What's wrong with this cutting?

I just got this one from a friends motherplant and we don't really sure whats wrong with it.
Someone maybe know?

...what was your clone method? What type of soil are you using?

definately looks like nute burn, from the potting soil?

I don't know what soil he uses or what clone method either. just got it a couple of hours ago, he have several years of experience, but couldn't tell either...he just said that the plant would like to change "environment" soon, so i took it from him today and will start raising it as my own little child, it's my first grow.

Should replant it tomorrow in a pot and new soil (if it's worth it, is it going so survive?)

It has a very complete rot-system all white and fine, and new small branches are groing to.
Should i cut the larger "damaged" leaves when they grow up a little bit (the new ones)?

is it rooted? Otherwise nute burn definatley.

I don't understnd what you mean, the roots are all white and alive, i planted it in a large pot with new soil earlier today.
But you think it's nut burn?
If it's nut burn what can i do?
Flush the soil?
