How do you take care of cupped leaves, leaves becoming wrinkly, and long
stems with spaced-out leaves. I dosed the tank with liquid fertilizers every
3-4 days plus weekly addition of iron tabs & Epsom salts. On top of that I
have placed laterite balls in the gravel. Leaves look very green on the dark
side so I don't think iron and magnesium are rpoblems. How do you get enough
calcium in then?
