Mold on new sprouts?

I have a simple DWC setup with lots of bubbles wetting the underside of netpots. Germed seeds were set in the pots with rapid rooters and hydroton 36 hrs ago. This am all but one has formed a small sprout with the seed case still on. All good so far. But 2 of them have a white fuzz on part of the stem. Is that mold? The rapid rooters aren't getting any wetter than when I used this method in the past, and I had no problem then. I took the humidity dome off. Is this a problem and what can I do?

Good first step on removing the humidity dome I have issues with it but only because I live in a humid area and its over kill, pics would help but wait for others to chime in. What are your air temps, water temps, ph, ppm's etc.

Temps are mid 70s. The humidity was being kept to 55% with a humidifier but I have let it fall to about 40%. There are no nutrients in the water yet, it is ro water. I'll take a pic and post soon.

I had green algae on one of my rapid rooter plugs when I was vegging in the dome.. What I did was cut it out with some sharp ass mustache scissors and it was gone , but did stunt the growth of one the plants ..

Cover the rapid rooter plug too so no light gets to it.

Looks like the seed spoiled & rotted yet still sprouted... I would personally (if you have more seeds & since your so young in its life) kill it & start over.

If you have the room let it grow then just make hash out of it
