Need help identifying this deficiency.
( Dos si dos clones )I feed calmag just about every watering. To hopefully rule out calcium or magnesium.
Growing in promix with foxfarm nute line under 600w full spectrum HID
Now week 3 of flower and spots getting worse day by day. Maybe p or K ?

Can you post pic of whole plant. Hard to tell anything by one leaf.
