Hi everyone. As you can see from the pics, there is a bit of a problem! These were taken from a healthy Blue OG mother, and I have just switched them to 12/12 today. Temps are fine, and good air flow/humidity levels. I also have 3 White Lavender in the same room that are fine...nice deep green healthy looking leaves. My PH is set at 5.8. and I'm growing in coco and feeding 20ml a and b to every 10 litres of water. Any suggestions anyone?
