Any idea what this white scale looking stuff is on the stem of this plant? It starts at the bottom and works its way up the stem. Could it be Powdery Mildew or a fungus? Please help if you know how to kill it or what it is.

Looks like salt build up are your leaves flat or curled and hanging down if there flat and reaching for the light that might be a disease if your leaves are hanging down its to much ferts causeing salt build up . Last chance if everything else is good it could be high humidity so the stem is trying to send out roots is posible
There is a pest called "scale" that bores into the main stem. They are oval shaped and flat and progressively move up the stem. The problem is when the scale dies it molds and the mold spreads to the node and surrounding bud. When you squash one, they are full of guts.
As Cougartex says, see if it is a living being. If it is use your nail or something to scrape them off, dispose of in a cup of real soapy water, then remove from garden. Scale, especially, armored scale usually needs a systemic to get rid of it. Oils, with repeated frequent apps, will control them. I would start with Neem. Good luck. -granger
Easiest way to tell if you have scale, is to check if the leaves below the scales are all sticky with a sugary substance. (They drink plantsap and shit sugar..)
You can scrape them off to begin with.
The scales protect them from many things, so you really need to scrub them off, the oils mostly kill the offspring.
You can use a toothbrush.
Edit. Better check the leaves too and try to get it before it gets to the leaves, though not all scales do that.
Also might want to quarantine these plants while you are dealing with this.
At the end of flowering, give the flowering room a good scrub.

those are pretty bad pictures but it doesn't look like scale. this is scale.
the white stuff.
looks like some sort of disease effecting your stem or maybe environmental stress. doesn't look like bug damage though. definitely some sort of cellular level issue.

Thank you all for the replys. It is not a bug as far as I can tell. But it does spread up the stem. I scraped it from the stems with a razor and under magnification it is not a bug. Maybe some type of fungus or something.
Soak a paper towel in alcohol and wipe. Make sure to put something around the base to catch anything that falls
Get silicone additive and mix into your nutes. Also spray or wipe on stems. You could also wipe with cayenne pepper
Amending this - if whatever the bumps are do not come off then most likely headband is correct

I could be wrong here but I would say your over doing it on your fert and that looks like salt build up from too much. This is what it looks like to me anyways . You never need to use the amount on the bottle always use a bit less as your grow is never as good as the ones they do the testing on stay frosty headband 707
