I am thinking that the red colored stems on the fan leaves is a cal mag issue. Started to see some rust colored spots on a couples of the leaves. Added 10 ml of gringo Rasta cal-mag to my water today. Will update if I see any changes.
Extra cal mag has seemed to be the answer also.
Day 60. Switched the lights to 12-12 three days ago to see if I could jump start the flowering on the two Hindu Kush. They are going to out grow my tent at this rate. They are 36 inches tall. Emailed growers choice and they said that with only 10% ruderalis in them they may need to be triggered to flower. Going to keep the lights at 12-12 till I see some flower growth and switch them back to 18-6 at that point and see what happens. I am a little disappointed about this and will probably not use GC autos on my future grows. Over all I think the girls are doing pretty good for my first grow. The smaller tangerine dream in the front left has some great looking flowers. Picked up a UV-B kit from California light works also.
the girlz are lookin great & luv the light rack! ppp
