What did you use for amendments and at what ratios?
I used Dr. Earth 4-6-3 and 3-9-4 at a 70/30 ratio. In 2 cu ft of coco perlite mix
Ok, few more questions: What brand of coco are you using? How did you prep it? Did this yellowing happen over night? Was the picture taken immediately after lights on?
I don’t remember the brand of it. It was an organic coco. I prepped it with water that was ph to 6 and added the perlite and amendments. The yellowing started at the center of one plant on the new growth and started moving out the leaves but only on the top set of leaves. Now the other two are showing signs of it as well. No the lights have been on about 8 hours.
