14 day old seedling, need help please!

[Letsgopens66]

I’m hoping this is just light burn. The plant looked extremely happy and healthy two days ago. Shiny spots showed up last night and it looks like the spots are dying today. Edges of the leaves are slightly curled down.

Seedling is in a solo cup with FFOF soil with 25% extra perlite. Watering with RO water, URB and liquid seaweed. pH 6.7.

Lighting is a viparspectra 1000w dimmable. 60% veg 25% bloom.

please help!

Just looks like light burn. Plain light photos are best. Make sure you remove any water spots after watering. Good luck

Looks like it could go into a bigger pot also could use some cal/mag, not sure though i don't grow in soil.
