What are you using for soil?

It looks like you polished your pots for the pics, never seen such shiny pots before. You make me feel like a slacker.

type of lights? how close? nutes? looks like to me heat rash. maybe a bit of nute burn or a combo.

the lights are 4 fluorscent tubes, 2 normal ones and 2 growlux, they are far enough from the plant not to burn it, i used some liquid fertilizer in the beginning but i stopped as soon as they started yellowing, and have not fed again, i also flushed them like 10 days ago and havent watered since.
