So they went Super Saiyan this morning...

These are the only two colas affected. Temps are 65ish at night and getting close to 80 during the day. Visible nutrient issues are from when I flowered and switched nutrient doses. The major discolorations are from a watering malfunction which left them dry for a few days.

Any help would be appreciated.

What grow medium?

If soil: get the bath tub ready because you need to flush the salts out. Seems like a nute lockout to me...

How often are you feeding?
