    Dinesh,

    Please give some tank and dosing specs.

    Are you using c02? How do you inject/diffuse it?

    Note that as plant bio-mass INCREASES so does the need for c02 and other nutrients.

    Have you upped these dosages to correspond with the new growth?

    If not, I would say they are nutrient limited.

    Sounds like it needs trimmed and the CO2 might be low, DIY O2 is often a dead give away if something goes wrong.
