Transplanted these clones 2 days before the pictures. Running these on a hlg 100 v2 led grow light in a vivosun 33" x 20" x 60" grow tent. Gonna have them veg in this tent for maybe 6 weeks before switching them over to the flowering tent. I've heard great things about Dark Heart Nursery and originally wanted napali pink. Ended up getting napali pink a few days after the other ones.
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.

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.
