I know this thread is long dead but to anyone who reads this in the future, thats not overnuting. Its pH being too high or low. read around some before you jump to conclusions, this symptom is often stated as over nute when in reality it is pH being off; nuff said....

I'd say you're both right... ph lockout caused only N to get absorbed which then caused an N over fert

Dark green leaves + Nutrient burn = over Nute.
