Maybe nutella.What the hell is that Grow medium?? Looks like clay! That's one sad looking plant dude.
I'm using a lot of nutella lately. Not in my grow, but hiking. Mixed 50/50 with peanut butter it goes good on tortillas. Occasionally when I smoke before cooking supper on the trail, I don't get around to cooking supper. I've had this problem at lunch too.Maybe nutella.
