too much light too fast , Chlorophyll production is way down most likely..

and Nitrites are a problem..

Suggest you keep up w/ a Seachem PRIME dosing till tank is fully cycled...

yeah 120w with LEDs seem like a lot but I don't know exactly which you are using. Also with that much light you'd probably need to be injecting CO2 to get the benefits. Ferts as well..

Beside that though, a lot of plants melt back and need to acclimate to new water conditions if they are much different than their origin. They may come back with some time.

As of now I am not dosing any ferts and I am on diy led light 120Watts total with red and blue.
If you have such intense light with an optimized spectrum, you better have plenty of 'ferts' in the tank and high CO2 levels. The plants are stressed already as they must adapt to submersed form (they were grown emersed). If you add lots of light and starve them they bleach.

So get that light way low, fertilize according to estimative index and make sure the levels of CO2 are adequate. 1 bps is most likely very little. Add a drop checker and go for light green at least.

It would also be good to have more easy plants to start with.

I added the plants to already established tank.

Can you please tell me the light in wattage to start with so that i can switch some led off for the time being.

Hard to do that without knowing a little more about

Light brand, lux, lumen, par, spectrum, dispersion
Distance from the aquarium
Size of the aquarium, volume

Any of these would help us make a better suggestion. In special look at jeffkrol as he knows his LEDs

Lights are osram branded 3W, distance from aquarium water 4inch, aquarium is 48x18x18 in inches and total volume is around 67Gallons or 250Ltrs.

I would say half of that to start with. If too dim or distribution would be unequal you could go to 80w. Keep in mind this is still just guesswork as I do not have any experience with these particular leds.

Some red plants might become greener. Just focus on survival and algae limitation for now so flow, fert co2. Plant grow rate can be adjusted later.
