As above I've spotted a white fluffy mold on top of soil on two plant pots as I've done a daily check it definitely wasn't there yesterday.
Question do I scrap the two affected or take the lot out? they're vegging at 4weeks from seed in canna terra soil, canna terra nutes. Shed grow under a 600w hps with oscillating fan going and a 4 inch rvk with rhinopro removing air to opposite side and out of shed.
Pics below but it can hardly be seen in pics.

It isn’t hurting anything except maybe your eye
Increase air flow

Yah if you let the top couple inches of soil get good and dry it will go away on its own.

I wouldn't stress about it though, molds that grow in/on the soil generally do not infect living plants.

Let the medium dry a little more before watering or feeding.

its no drama to my eye. its will it affect the finished product? I've never had any type of mold in past thats why I'm a little concerned.

Means you have healthy soil. It’s not a bad thing. But the moisture that’s allowed it to bloom and live is not the best thing for the roots.

tbh i think I may have over watered them as they're slightly clawing. Will allow for a better dry period before next watering.
