White things growing on my carrot ferment? I'm a newcomer to the world of lacto-fermentation.

I've previously made my own sauerkraut with great success, and thought to dip into the unknown and try lacto-fermenting onions, carrots, and beans.

I did so by cleaning the jar with boiling water, wash the vegetables, adding water, salt, and some brine left over from the sauerkraut ferment.

It's has been 2 to 3 weeks when I check my carrot ferment today. There are quite some white growth on top. It has a faint alcohol-like smell. Does this mean it has gone off and unsafe to continue?

EDIT: Browsing the internet, seems to be either mould or yeast. I don't want to chance it so I am disposing it.
Throw it away and start again. How much of that liquid was bribe? Something went wrong. 
It looks like you added too much liquid.  You only need enough to cover your vegetables. I would use 5% by weight of salt for this type of pickling. For example, if you use 100 pounds of carrots, then add 5 pounds of salt. 

Don’t give up! Try again
