Getting stem root where the lower stem weaken's and gets smaller. Using rock wool and sometimes its turning green when it starts yellow. This happens in veg only under a 200W CFL and when the seed is about 3 weeks old.

Things I'm doing:
-Its not from water level being too high.
-Could be from covering up the net cup w/reflective mylar? I could a hole as big as a quarter so the seed can grow up through it. I do this so light doesn't leak through net cup and get into my rez.
-Only putting 1-2 layers of stones in the bottom of net cup..

Whats doing this??

I had it on a huge plant my last run, got a black ring around the crown (base) of the stem it eventually got mushy and ate into it pretty deep and then it eventually just went away (lucky I guess). But the stock was very large, got a huge knuckle above the mush ring and finished out flower. Unfortunately it’s a pathogen and is inside your plant.

Also could be a borer insect, but ether way if the plant is young it more than likely won’t recover. My plant was big and aged so it could fight it off I guess.

Stem rot definitely a advanced form of root rot. Algae is a good sign root rot (pythium) is can be around. Had algae suffocate my roots, it will work it’s way all in your system. If you have root rot, get a healthy dose of h202 at 5 ml per gallon ( for full grown adult) and was the roots a couple times a week. If you see foaming then it’s working.

Most definitely does happen, 100%. Ive had it too. I had it from "trenching" outdoors. Sometimes shit happens.
