So @ChefDGreen can I ask you a couple questions about your Killer A5 Haze?
Is she fed along with all the other plants? Same strength nutrients as the other girls or does she get something special?
Consider waiting till her pot is light and mix her a gallon of water with 4 grams of MC, 2ml of Cal/Mag, and see if you notice any difference in her appearance. If you don't see a difference before her next watering then go back to what you were feeding her.
