Yeah Im gonna let it dry out a bit before I water again.I don’t think I’ve seen algae yet in soil (could be due to my constant underwatering before blumats) but if that soil has too lil of perlite where it stays damp to long I suppose they could get algae! Also possible that soil had a microbe product added to it so was already there! Whichever it is cutting back on water it’ll def go away! Mine grew like that underneath earthbox cover but they’d grow microbes that looked like a thick ass cloud on top of soil!
