Noob leaf problem

New grower here experiencing some kind of leaf issue. Day 12 of my seedlings and I noticed some of the very tips of the leaves are turning up. Nothing has changed in the tent since the seeds have popped. They are still thriving in my opinion, I’m just not sure what the leaves are telling me. Just trying to take care of whatever issue before it’s a problem. Google search said underwatering, overwatering, nutrients, too much air movement or light lol watering PHed water whenever the first 3ish inches are dry. thanks in advance

3x3x6
Strawberry cheesecake auto

3 gal fabric pots
Phlizon “1000” watt full spectrum cob
4” exhaust

Temps 75-79 RH 50-70

It seems a tad dark. It may be an issue relating to too much N but really it looks fine to me and if it’s N related it will grow out of it. Just keep watering.

looks fine id see if it manifest but as of now id keep going just dont do to much and use each grow to learn you cant rush experience. If i do recommend anything is to defoliate and use as large of a pot as possible and even that requires technique and refining.
