It looks like over watering

There definitely could be a little bit of that going on, definitely let it dry back.

I don’t believe that is a nutrient issue as much as a temperature issue. And if it’s in a living soil it’s more likely a bit of a nutrient burn the yellowing is but the other stuff is temperature issue I believe.

People don’t think about temperature of the soil the soil a lot either.

The issue you’re seeing is not nutritional. It’s physical stress/damage to the roots. Looks like multiple compounding issues.
-
maybe the light and watering issues i have roots trying to grow out of the pots already so would there be root issue’s ?
-
Ideal soil moisture levels are between 60-70% (for microbes) with available oxygen being a huge factor for root health. Damaged root hairs take time to grow back before you’ll see any noticeable difference in growth.

So would that essentially cause nutrient burn/nitrogen toxicity because the roots are stressed and can’t absorb the proper ratio of nutrients creating a lockout? I initially thought nitrogen toxicity/lock out/heat stress from the pics.

Roots uptake minerals in an ionic form through root hairs called trichoblasts. Under-watering dries them out so they die and no minerals can be adsorbed. Over-watering suffocates them from lack of oxygen so they also die but with the added chance of mold.
