Hi Jermaine , i'm not liking how the WWs are going actually, that's not looking good to me. I think you're experiencing PH-related problems due to an irregular or insufficient watering schedule. I can't really see how much you've been watering but i've had the same problem as you. If you're incoming PH is 6, the soil buffers it out to 6.5 and this is causing some sort of difficulty for the seedlings. If you're feeding 6.5PH and the runoff is 6.0 then your soil is not doing it's job buffering the PH and this is causing these problems. Sometimes if you let the soil go too dry, or stay to humid, it will mess with the PH and cause these wilting issues i can see in the pictures. Only thing you can do is not let the soil stay so dry for so long and avoid over watering, stick to a strict wet / dry cycle and water water feed water water feed schedule. This should allow the seedlings to recover, and grow BIG ! So to answer your question : it's a mix of totally normal but slightly unstable genetics in the early life of a plant (not so bad!) and PH-fluctuations causing nutrient lock outs and difficulties for the seedlings. Hope this helps ! 🚀
