So I have 4 seedlings growing (1 is 9 days since planting, the others are 7). I noticed that their growth seems a little stunted compared to some photos online at their same stage. I noticed that the oldest one has slowly turned colors from a healthy kelly green into a more lime green. The leaves look basically healthy and the color change is uniform. The other seedlings are healthier looking, but I noticed their color is slowly changing as well.

I took a pH reading of the soil and from the color guide, the pH looks to be around 6-6.5. Could that be the problem? I know yellowing in more mature plants means N deficiency, but these seedling only have one set of true leaves and a very tiny 2nd set coming in. Any suggestions?
