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.
