To be certain I would feed her some Calmag and a halfstrength bloom boosting product that has high potassium content the reason for this is she definitely doesn't need nitrogen

It's a bit early to say. First pic looks like calcium. Other pic's suggest maybe potassium, or a Boron deficiency. Until it progresses a little more it's hard to pin point. But it's certainly narrowed down to those 3.

With the rust colored spotting showing in picture 1 I’d say calcium is needed

Moist build up at bottom - overwatered I believe this seedling had too much moist. The soil was moisty when I filled the pot. Somehow the pot feels very heavy now and seems there is a build up at the bottom. I made some airpockets to the bottom. Should I wait or take it out and put it into a cup and dry the soil?

Week 1 new clones' top leaves are not solid green. See some minor claw.Already after about 4 days out of the moisture dome, the new top leaves' color doesn't look solid green throughout, and doesn't seem to spread out nicely. I've added some nutrients from Fox Farms with some molasses and mycorrhiza, but no improvement. Anything to worry? 😕

Yellow spots on bottom leaves.Starting to notice big brown/yellow spots on the bottom leaves only. Plants look healthy at the top but not happy(not praying and look droopy). I water every 3/4 days so it’s not a matter of being locked and Calmag is also used. Can’t figure out what the problem is here.

Day 67: after watering, I am noticing the leaves curling under, but fine next morning - or at least less clawing. Does this look like over watering? Watering every other day 1/gal per 7gal fabric pot with 2/3 soil, 1/3 perlite well mixed. If not, what might cause the claws?
