Green Crack. First Leyla's Fantasy

@Fast_Buds, hi sorry for annoying you with this but i am just on my very first grow and cant seem to get my seeds any further than them breaking the soil and them just reaching around 3-4 inchs with them first 2 orignal small leaves getting to about -5/7 cm and then thats it she wouldn't grow or expand any further and that was after 2 days staying at the exact same size so i thought it needed water so i give it some but it then went lymp and started to just get smaller after that point to the stage where it was almost completely closed up again so i assumed it was dead so i just give up all together and well now i have one seed left which is in the papertowel for the next 18 hours or so then i put that into the same medium as that other one that died on me which is coco the one's you buy from a cheap store and you add so much water until it swells up then just fill up a small pot with holes in it and hope for the best once again but if you could help me out somewhat as to what might have gone wrong with my last seed so i get hopefully a lot further with this seed you know i would be so grateful for any guidance you can give me here thank you so much in advance and i really love your setup here great work guys.
