how much PH down 75% do i need in 1 liter of water to lower my soils PH to 6. I am growing in miracle grow, and can i also add CAL-MAG PLUS in the water to?
I am growing Big Bang Auto Flower from Green House Seeds and 3 weeks in i am getting these burnt looking leaves my lights are 3 1/2 inches away and i am using 3 36 watt cfl's. I have seen a few gnats but i kill them as i see them and i spray the leaves with organic insecticide spray.
