Looks like iron excess. Are you using tap water? It might be kind of hard. The other thing that comes to mind is a minor element lockout due to P or K excess.

Little chilly at night. Plants grew well, did a little snipping. Ended up moving the napali pink out of the tent. These girls easily filled this little setup.

This honestly might be it. Didn't know water could be hard, so we checked my local city water quality. Not the best, we asked our local hydroponic shop what we could do. Apparently, leaving the water out for at least a day lets the chlorine and such naturally evaporate away. A bit inconvenient but gonna start doing that and see if it makes a difference.
