Really dont know, i growed 7 times for now and all time use this mix. Coco brick is easy for transport :)
What do u thing about reuse soil? and add 50% new soil all new grow?
I was watering today and measuring runoff and pH
Ph: 6.3 That's what I think is okay
Runoff: 3 EC That's probably a little too much
So i think i have nutrient burn?
Any idea what can be problem. Now is 6 week of flowering. 1 week before that were still beautiful and dark green. But now they have begun to turn yellow slowly. I think I burned them a little with fertilizer, but I don't know why they started to turn yellow now. The previous grow the same thing...
