My one plant is sick, the leaf color changing?

Here is a pick of my 45 day old 3 gal pot GG auto girl, it started this leaf color changing 4 days ago, I have been watching all my numbers, water ph 6.6, have been using superthrive with ajusted ph and here is a photo of same plant in a 5 gal pot. Anyone have an idea as to why one is healthy and the other is sick? I have treated both the same.

I’m not an experienced grower and I’m in my first DWC grow but signs appear like lack of nitrogen. Hopefully they’ll perk up by next feeding.
