I don’t see anything other than pH that is off. Is it possible that over or under watering is the problem? Cannabis like wet/dry cycles and seedlings need very little water.
A pH of 6.8 is too high for coco. It should be around 5.9 or so. Check the hydroponic range in the chart. Coco should be in hydro ranges.
Looks like really wet coco with perlite. I don’t see any issues really besides high ph and looks to be no drainage with those cups but I could be mistaken as you can’t clearly see the bottoms
Ph to high and appears they may not be any holes in the bottom of them cups. That coco is very wet and the tray they are in is extremely dry and clean…
Look i agree with the other members about the ph but do u have drainage holes in the cups if u dont u could be drowning them,yah thats to wet for seedlings bro let them dry out nefore u water again
