hey! a couple of my seeds are turning yellow and i dont know why, i water them with ph of 6.5, the temp is 75, and i have two fans running and a 1500 watt led. some of the seeds are thriving but one or two are starting to yellow. any suggestions?
 
Do you have a pic? Environment is crucial. Why 2 fans? And how old are the seedlings? What grow medium are you using?
 
i will try and take one. i just used two to get more airflow across them, and they are over a month old but are just now starting the second set of leaves. i wasnt using the right ph water until two days ago.

It seems like your answer is in your response, it possible improper ph can and will stunt growth
 
It’s possible depending on pheno type and if the plants genetics are used to high humidity then It would make sense. For the most part I Am a outdoor grower so I deal with Mother Nature but my grow right now is low 30 humidity and it’s just fine. Here is a website that explains VPD https://www.dimluxlighting.com/knowledge/vapor-pressure-deficit-vpd-calculator/. Lots of science behind it and people swear by it, but I also know lots of people who grow in low humidity without any problems.
