As latewood said it depenps on the stage. Mine runs from 1500 to 2000 PPM's in the middle and end of flowering. More important is you lose the nitrogen the farther into flower you get. I found out the hard way, don't even tell your brother about it. Since we all know now we will be at your place for the trim party feb 18. LOL
