That’s just some soil fungus that’s forming. Likely the soil is taking a long time to dry out. Nothing to worry about. Just get a fork or a small hand rake and break up the surface of the a soil a little bit and it will disappear. Breaking up the surface of the soil will also help when you go to water next time. If you leave it as it is once it’s dry the water won’t want to penetrate that top caked up layer. No sress, no seeds, no sticks.

Nothing to worry about, Looks to me like its some mineral/salt buildup from the liquid fertilizer you use. This is common and happen when the medium starts to dry a bit. Just ensure you getting about 10-20% runoff everytime you water and it will not buildup to the point of toxicity or lockout causing more issues down the road.
