I'm using aqua flakes a n b only. I need a tad nitrogen supp....but haven't gotten. just HnG a and b. set it and forget it. I set ph one time at six.I have had this guy in veg for a month in perlite and 7 to 9 weeks in dwc. I am now up to 10ml a gallon. Bit purple but it's now going away. Do you guys think I need to worry about leaf veins. Looks like N or mg/cal...I don't want to hurt it so I let it be. Any help first time
