Plants absorb nutrients mainly from the roots; also, if you're adding, say root tabs, or something similar (to fertalise the soil with potassium and iron), then these chemicals will leach into the water column for the leaves to absorb, anyway. I just don't understand it; and the high volumes, too: every week?! Really? I'd have thought that lightly fertalising the soil every six months would be more than good enough: it is for my garden lawn. Can anyone help me out with this?
