New Root!!! Bad Root :(

[TheCanfield]

Hello again all,
So I took a look at my baby the other day and this is what I saw... an new root... initially I was all excited that after my hacking and repotting (Click here if you want a refresher of what I did.) I finally have a new root starting



Although the new leaf on top is growing the others are looking bad


The smiley is because I was bored

Upon further inspection I noticed that the base of my brand new root is looking all black and nasty and after digging around a little the other roots don’t look any better at all



I feel as though there is something killing all my roots...I don’t know how its all fresh medium from my last repot ....what I want to know is what to do next ... and to hack off any and everything that is black dip the nub in a rooting powder and go from there but I don’t know if that would work.....my other idea is to try and air layer right above the bottom 2 leaves and once I have nice roots (if I get nice roots) repot...any help would be wonderful
I was so excited to see the new root all green and w/ a bit of waxy looking to it like the pictures show....none and I mean NONE of my roots look like that and its kinda disheartening hehe
ThanX Again!!!
