Annual Grow

@Sp1ker, it could be a fungus possibly..(septoria).. . also could be burns from the light if water left on leaves after watering, nitrogen deficiency usually starts at lower leaves and works it way up plant.. not necessarily yellow spots,,as for northern lights and nitrogen, they tend to love more than most strains....so not being there, these would be things I would consider

@spyder, Thanks! The northern lights isn't looking too good - lots of yellow spots on the leaves. Do you think it could be a nitrogen deficiency?
