That is alot of root juice, have you seen the bio bizz schedule? They recomend giving auto flowers the all mix schedule whislt also growing in light mix... so 1st 2 weeks water.. then 1ml of biogrow, 1ml of root juice, 1ml of algamic 1ml of heaven.
@@OrganicLivingSoil, didnt take that into account, thanks for the info! I once had 2 autoflowers which had no problem with the amount, but now with 4 and the same lights, i maybe have to go down a bit
