They new leaves on my amazon sword are coming in pale. I looked it up and the only thing I can think that it would be is low iron. I didn't have this problem until I added more plants to the tank and I think because the Wisteria grows quicker the sword is having a hard time competing. Is there any way to add iron to the tank that is cheap? I don't want to have to pay for some fancy plant fertilizer at my lfs if I don't have to.
