spots and curling leaves?

i cant decide if this is nutrient burn or a lack of something. ive been flushing for 3 days now. and i keep getting this probleem of these yellow spots and the leaves feel crispy and are dying. its day 36 of flower. im using a 250whps and both are in soil. im using miracle grow as this is my first grow and its all i had. whats wrong them?
