Is a root accelerator necessary for autoflowers? What do they have that other micro/grow/bloom/calmag dont that help assist the root enhancement? Or are any of those in low dose similar?
My last grow I used Recharge. I was pretty impressed with root growth. I don't know if any plant really needs any root accelerater, but I will use it again.
I only loaded my coco with a premix of nutes for her to hit around week 3 and she's doing fine. But not sure if it'd do much as they have such a short lifespan. Give it a go and see what works
