These plants are about 3 weeks into flower under a 600 watt air cooled hps about 24" above plants. Room temp stays around 72. Humidity around 40. There being grown in 100% canna coco with canna nutes. I just did a flush with no change in the plants. PH is at 5.8 and at 700ppm of nutes. Canna A and B 5ml each pk14 at 3ml gal and calmag at 3ml gal. Any ideas about the yellowing would be helpful.
