Young Plant Yellowing, Please Help!

My little plant has been yellowing and I'm struggling to understand exactly what the issue could be. I have posted more detail in my grow journal here(with some history) : https://www.rollitup.org/t/nahmloss-journal.1016479/post-15540116

I think it could be any of the following issues; light stress, ph inbalance, over/underwatering. The plant did suffer a small bit of root damage when I transplanted it a while ago. I also feel like the growth has dramatically slowed down compared to the first couple of weeks.

Your plant doesn't appear to be wilting, so I'd rule out moisture stress.

Be sure to soak your pots until water runs out the bottom, then let them dry until they're light to lift.

Have you fed her yet?

Thank you. I fed some diluted liquid kelp fertilizer for the first time yesterday and did a full soak. I think the plant looks a bit better today, a bit more even.
