Looks a lot like calcium deficiency.

Ph of medium
Something you did changed the ph of the medium. Without more info it's hard to tell from just a pic. The whole backstory would help. Eg why is there buckwheat in your pot.

Necrosis is what that is called, it's calcium deficiency usually. As @Jjgrow420 stated it could be pH or you may need to increase base nutrient strength in my opinion. I think you're using rice hulls? Are you fertilizing them with liquid fertilizer or?

It does seem to be a calcium def. I’m not using any chemicals on them. Only organic nutes. My first attempt at a living soil. I’ve given them some organic liquid fertilizer and top dressed them yesterday with some good goods like compost,worm casting, bone meal, blood meal. Hopefully that fixes the issues.
And I’m using rice hulls as alternative for perlite/pumice. As well as covering the top layer of soil for more cozy for the micro babies.
This is how they look now

How close are your lights? Do you do any foiler spray? I ask because one time I burnt some leaves cause the light was a little too close, the leaves had little spots where the droplets of water stayed on the leaves. The droplets magnified the intensity of the light. Or I think that's what happened.

Lights are in a good distance right now. But I get what you mean. It happened to me on thus same grow. But these dots are a calcium deficiency.
