Auto Seedling Issues: Help!

[Slim Jim]

Growing 2 Auto strains from Ethos Genetics: 2 Banana Daddy & 2 Pluto Cut. Everything was perfect and suddenly at around 6 days from sprout in soil one had two small dots. We thought possibly water droplets although we were very careful. Then more on the other leaf. Now 3 of the 4 are showing issues but all a bit different. I moved the lights a bit higher today just in case-but had them in manufacturers suggested distance.

1st Pluto Cut: 2 sets of spots. No pests under scope. Looks like thin spots in leaves:



2nd Pluto Cut: two leaves show pinching with some dapple spots. No pests under scope-mites?



3rd Banana Daddy: just has that mild dappling showing up. Was fine last night. May be fine.

Conditions:
Roots Organics Original Soil
1 600w LED 30in away (was 28)
1 1000 w LED 34 in away (Was 30)
70-75 degrees
55-80 RH
Water only

thanks to anyone that can help!

How often are you watering? The soil looks quite wet. Overwatering can cause spotting like this from my experience.

I wondered if that could be an issue. Originally I literally misted it. Then began to add small amounts moving outward each day but not a lot. Last night was the first time I actually watered the pot. And one of them is perfect even though I’ve treated them all the same....

Here is how it looked before I watered the pot-just small circles like if it were in a solo cup.

It looks like it's been fed too much what soil are you in? Is that miracle grow? The little yellow fertilizer balls give it away...Back off the watering, til it droops a little then water only when the pot feels light

I believe you are right. We thought we had Roots Organic Original which would be perfect. It was Green Fields which has high Nitrogen. The leaves are pretty dark green & some rust on the original leaves which led me to think calcium deficiency from higher nitrogen. The good news is they look GREAT now at 15 days from seed!
