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.

Our Black Jack was suffering from some burning in the leaves, we think it might be a lack of magnesium but we did let medium get dry a bit so that also could of been a reason. We also added a scrog net and pushed down on the branches so they can stretch sideways and support the weight that is yet to come. And now that the scrog net is up, they are entering the first day of flowering.

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.
