Now that I'm retired I've decided to grow my own. I have 4 little ones with a problem already. As you see in the attached photo the leaves have started to turn yellow. All 4 are the same.
I have the light adjusted to 50%. On 18 off 6.
Anyone with any advice would be greatly appreciated for the old man.

What is the pH and PPM of the soil runoff?
I agree with @TnA Homegrown and suspect the soil may be a little hot for your seedlings.
Auto flowers are more sensitive than Photo Periods when it comes to nutrients so people usually feed them less. At this point these is not much you can do except power through it. Just keep watering with PH balanced water and keep an eye on them. They should eventually get over it if this is the problem.
Let us know if the problem spreads to the higher leaves and get some nice close up pictures.
Good luck!
Poor girl. My grow method would be to of had that plant in a much smaller pot. I don't think she is ready for that big of a fabric bag. Good luck!
The Black Gold is garden potting soil, correct? Perhaps is a little too hot of a mix for them. Just a thought. Good luck 🌱🪴🤙🏻
