I it could be a few things, how much are you feeding in ppms. I'm think to many ppms, ph issuse, is your nutes compatiable to coco.....
Havnt put any nutes in it im popping more seeds now well see how it goes
were there already nutrients in the soil?
Coco has nothingSeedlings will die without coco nutes or formulating some other feed.
light's too close or, not watering often enough maybe, bad air circulation, those peat pots or pulp pots might dry out fast,whats the watering schedule? it looked like dry soil
Looks stressed to me...Tell that to this 12 day old seedling View attachment 2310805
