Bad seed? Or something else?

Got a lot of good feedback here, I germinated them and planted them in the same medium and watering cycle as all the other seeds in this grow, total of 6 plants. There are tones of holes on the bottom and sides of the yogourt container to let it air prune, they where made with a small screwdriver. All the other plants had no issues coming up, and when this sprout first emerged it was good looking just like its sister airlines plant. This is somewhat like what I have experienced with LSD-25 from fastbuds. out of 5 seeds, only 2 made it the rest popped up and died and one that did make it was only 5 inches tall, from what I read online it was the companies fault, but other have stated they have fixed there bad reputation in the previous years and shed there nickname of fast duds. but IDK, I have a very mixed feels about the company and there products. I do not think it is fertilizer burn as the other plant should be showing the same results, also when autos get to much fertilizer I have known them to mature really fast and only grow to about 2-10 inches in height. This happened a few years back when I planted some in "hot" soil "blackberry and LSD-25" but the photoperoid strains did just fine. So from this I feel its an auto type problem. I also can see how this could have been a result of the growing medium and it being to wet and heavy, being mainly peat, I normally mix in extra perlite and worm castings but this was getting transplanted so did not do the extra steps as I would a full indoor grow. bottom line I feel its a bit of A and B, 'A' being genetics and an auto, and 'B' being average not the best wet medium.

Salut le jardinier! C'est une mutante qui risque de mal pousser ou d'être au ralentis. Bonne chance à toi

What is your Ph and Ec worth? and yes it can be genetic :-)

Just from the looks of it i'm going to guess you might have a drainage issue. Did you poke lots of holes in the bottom? or just a few? I'd suggest just perforating the heck out of the bottom of those containers and let them dry out a bit! Other than that Enjoy the Grow!

How’s your drainage? How much water have they received? Looks quite wet to me, I’ve had a similar problem before where the medium was that wet and packed together the roots couldn’t penetrate or breath. How ever I’m no expert😂👌
