looks like your little seedling pots dried out. I wouldn't give up just yet on these. Do water the little pots though... Don't superficially water, don' spritz it.. you should always fully saturate. If such a simple act ever causes a problem, it is the fault of a poorly constituted substrate and nothing else.
Seedlings are more senstive to dry substrate since the roots are not 'deep' on day 1. Within a day or two the taproot is down near the bottom, but you still don't want large portions of the substrate drying out at this early stage. It shouldn't have dried in 3 days, either, which makes me think it wasn't fully saturated to start.
i'd suggest not using those pre-formed peat puck or peat pots etc. They tend to be too acidic and when you do fully saturate, they are way too heavy with water and has a poor gas:wate mixture. More perlite or similar is needed for that sort of medium, which it has none. high water capacity substrate needs 50% perlite or similar amendment for drainage/aeration. Something like coco, which holds significantly less per volume, only needs 33% to achieve similar aeration properties.
Keep it simple.
1) fully saturate small seedling pots with a substrate with proper aeration
2) compress a small divot 1/2" deep (a knuckle). This provides a good basin for the seed. Can't 'fall' deeper into the substrate etc.
3) Cover with media from the sides and gently tamp down. Dark and moist is all that is needed.
If the small seedling pots dry out too fast, use a humidity dome until they start to sprout -- unless you live in a desert, then you may want to use a well-ventilated dome to provide an appropriate level of humidity. I don't want to irrigate before it sprouts. Once they fully sprout, you know that taproot is not superficial and won't die if the media slightly dries at the top.
Irrigating - stick to plain, ph-balanced water. Unlike a more mature plant, don't wait as long between irrigations the first cycle. Usually with soil, you'd wait for it to dry 1" deep. before repeating. Don't wait that long for the first re-irrigation. Again, you don't want the media competely drying out for a seedling. After that the roots should be established for a better wet-dry cycle and allow more dryback to occur before irrigating again.
One last tip -- if you get too many sprouts with a seed shell still attached, bury slightly deeper in future. If it happens rarely, that's fine. Too deep will cause extra long sprout times and too shallow means you have to remove a seed shell from a delicate seedling... should be fine 99% of the time doing so, but better not to maximize the occurence.
