Dude guess what?? I just found out the problem and it’s low humidity. Low humidity in veg closes stigmata and causes calcium deficiency. Im in slapping myself, because all this time I was so happy with low humidity, since I know no mold will grow.

For the clones, you mean? I think new clones and young seedlings like a bit of extra moisture, and there's no worry about mold at that stage except for rotting off of the shoots (if you don't allow soil to dry out slightly between watering). I think some strains like to be damper as babies than others do! More research and experimentation needed!
