Seedling yellowing in middle

[LiTit]

I am a first time grower with 8 seedlings and while the seedlings are looking pretty good (day 5 after coming out of soil), the middle of the first node is turning a green/yellow mix. I am using a 35w grow light that is 2 inches from the canopies. Also, I put them on a windowsill when the sun is out.

Is this too much light? Overwatering? Nutrient deficiency? Or am I just worrying too much?

Fill the containers with medium. Water lightly and be patient. No nutes. Window light is weak.

Thanks for the reply. I am watering once every 2 days, and I will leave them under the grow light instead of window light. I am using Miracle Gro potting soil as the medium at the moment. I plan on using a different medium when I transport to 5 gal containers.

Put some more soil in there and soak it
There is no reason to water seedlings every two days
