It's organic potting soil and no I haven't used any worm castings it'll be 3 weeks old come day after tomorrow. I've read that you shouldn't feed til the cotyledons start to yellow. My plan was to feed Saturday by then it would've been 3 wks old.

I’m curious how you grew a plant with no nutrients? Temp and RH are weird

Suspect

Looks like too much water. Are you letting the soil dry back before watering again? Whether you need nutes will depend on if the potting soil is amended.

If you still have the soil bag or can remember the brand you should be able to figure out if it contains nutes. Most good commercial soils have some nutes, at least enough for 2-4 weeks.

Yes I'm letting it dry out between waterings I only watered twice since germination. After it sprouted I didn't have to water for bout a wk. I watered enough to last a week and watered again this passed Sunday.

its not necessarily that you dont have to feed until the cotyledons start to yellow, it's that if they are yellowing off you need to be feeding.

Can you take a more focused photo possibly? It's hard to see the damage on the leaves clearly in the last photo. but with the info you give here i lean towards a PH drifting acidic. First pic looks like maybe overwatering, the progressed damage doesnt. that looks like some kind of nutrient burn or acidity issue.

Temp needs to be 72f to 75f unless you have CO2 then you can run it at 85f. Humidity should only be 60% for veg . Give them worm tea from the get go it only strengthens them or top dress with it water it in. Try to add some perlite to the soil you are using at a 70/30 ratio. Compacted soil makes cannabis unhappy.

Always let your soil dry about an inch deep first knuckle rule.

I marked in one of the pictures what it starts off as before getting to this.I tried to get close enough to see it but it's this grayish silver looking markings on the the leaves and wherever those spots are is where the leaves get really soft and wrinkle looking.

Go easy on the nutes, don't blast it full strength. Start with about 25% strength and gently work up. Vary easy to burn young plants
