Noob question here. I noticed these white spots appearing on my substrate recently that look a lot like the trichoderma I’ve dealt with before with mushrooms. Sounds like trich isn’t much of a concern with plants. I’ve also seen some folks say that nutrient salts can look similar to this. Any insight as to what they are, if I should be concerned, and what do do if they’re an issue? Thanks!

That dosent look like salt to me, but id wait for someone with more experience to weigh in.
Some kind of pin mold.
Whats your water your using like? I kinda have something similar but from putting tap water woth lots of crap in it into my humidifier. Does kinda look like mineral build up to me but im new to this. Try picking some up and then kinda letting it fall in the air and see if it raises in the air like floating or spores would or falls straight down. Also more info like your humidity and water your using would be helpful to figure out whats up
