Orange Juice?

my dad used to grow when he was younger and he said he would feed them orange juice is this good to do?
if so how much orange juice would u sue and would u mix it with water or jsut straight oj?

Well the pH in orange juices is more acidic (3.3 - 4.3) that what I believe is needed to sustain a healthy plant so I would think it might not be healthy for the plant, but hey, I'm new to growing marijuana so don't take my word for it just yet.
