New tank plants withering


I expected crypts to melt and some have but some others are withering such as ammania gracilis and rotala indica. And my limnophilia aromatica is melting.
These have been in my new tank for about 6 days.
I have yet to hook up co2 and dose fertilizers. My ammonia is 4ppm(started fishless cycle) nitrite 0.25ppm and nitrate is 10ppm. Lighting is 4x54w for 265 gal tank. So less than 1wpg.

It will take me another week to complete co2.
Whats causing these plants to wither and melt?
Should i dose fertilizers and metricide right now?
Will these plants come back to healthy status once everything is set up and stabilized?

I would advise you to, SLOW DOWN

Wilting/melting plants are stressed, blasting them with nutrients it only going too give you an algae farm at this point. Chemical warfare is not the answer.

Just wait. All plants look like they melt in their first week or so. They'll turn around.

some people in my local forum are saying its all because my lighting is too low.
saying even if i run co2 and ferts, because of low light plants cant use them.
is this true?

do i really need more light? if so how much more?

All plants use ferts and co2. The difference between high light and low light plants are their ability to use large or small portions of what is available to them.

Obviously higher light plants will use more of the available nutrients, where as slower growing low light plants will use less.

obviously 216W in 265 gal is a low light set up.
but in my current light setting, how would med to high light plants do with co2 and ferts?

Hold on there. You cannot just apply the WPG guideline blindly to determine how much lighting you have.

The WPG guideline is only applicable to T12 bulbs, which you likely do not have.

In addition, the WPG guideline was not designed for very small nor very large aquariums (your aquarium obviously falls in the latter category).

What type of lighting do you have?

So, you have two rows of bulbs across the top of the tank, and the two rows are roughly 15 inches apart? That means each spot on the substrate is getting light from 1 bulb, about 21 inches above that spot. If those bulbs each have an AH Supply quality reflector, you probably have 35-50 PAR, good low light to medium light. But, if the reflectors are not nearly that good (white painted flat surface behind the bulbs) you only have about 15-20 PAR or very low light. And, if the bulbs are in a tall canopy, say 6 inches above the top of the tank, you could have way too little light.
