Best advice ever!!

I was wondering if this could also be a low lighting effect and the plant
was diverting its resources into root production rather than leaf production.
Does anyone know if exagerated root development is related to poor lighting?
Having said that, I do have 2 Watts/(US)Gal which with plain gravel and no
CO2 is probably OK; as Paul noted this plant was in a localised area of shade
due to the monster swords.
