I would just put straight ph'd water in the res til you start to get green vegetation again. When you begin feeding again after green veg is back, run it appox 1/4 of what you should. Plants that young dont really need too much for nutrients. They are building root mass more than vegetation at this point.
I dont believe its hungry. It would be eating itself if that were the case, and all the yellowing is in the new vegetation.

Yea seedlings can do well up until around 10-14 days...

I say give it half dose or even 3/4 dose and see how she responds. Looks hungry

That doesn't make a difference. It's either underfed, too high pH, or both. I see deficiency, particularly iron.

A lot of people will say to start DWC with tap water or very low nutes, but this limits seedlings in their first few weeks. The minute nutrient levels are raised to a sufficient level, the plants always start taking off. There's no reason to purposefully starve seedlings...
