6 Afghan Kush Ryder(Auto flower).The ladies are 4 weeks old and the tips of the leafs are starting to yellow, otherwise they are looking good. Bubbleponics DWC. They are 8 inches tall from seed. They are under 600w Hps 36 inches from top, on a 20/4 schedule. PPM is 800, I got my PPM meter when they were 2 1/2 weeks old and the initial reading was 1930 so I added 2 gallons of water to the reservoir. My PH has been a steady 6.0. , Temps range from 75 to 81 degrees F. Im guessing that they were over fertilized. What is the cause and how can I correct this???? Thanks in advance for any help or comments. Will post pictures later on today when I get my camera.
