The week got colder than what we'd like. Seems like the nutrient deficiency for blackjack stabilized. There is no new damage and the leaves didn't get worse. Can't wait to see these girls in full bloom
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.
