There are many many reasons if you ask me....We need more info from you..[:] ..What kind of lightings do you have? CO2? pH/KH? NO3? K? PO4? Traces? GH? and etc.
Hi,
In what circumstances will plants' leaves turn yellow??.. sorry but i'm quite worried.

Plant Physiology by Taiz and Zeiger
Please include the name of the plant. is it cryts or gloss or what. More info please
I think my plants are similar to this - Hottonia inflate . but with finer leaves..
in what circumstances will they turn yellow huh?

the lights i have right now is 2x55w(on for 6hrs, then 1x55w for 5hrs),
co2 is 2bps=30ppm
ph is 6.3
nh is 0.2
no2 is 0.5
kh is 2dg=36ppm

Resistance is futile, you will be administrated!
How does 2 bps of CO2 = 30ppm? I hope you are deducing 30ppm form your KH and pH values.
Anyway, the problem is most likely the lack of NO3. 0.5ppm is kinda low for a high light/CO2 planted tank. Push it up to 5 to 10 ppm.
What is the size of your tank?
Vincent - AQ is for everyone, but not for 'u' and 'mi'.
Why use punctuation? See what a difference it makes:A woman, without her man, is nothing.
A woman: without her, man is nothing.
if the plant is really Hottonia inflate, then one important requirement is the temperature, they wouldnt grow at temps above 26/27degrees
ya hi, my tank is 2ft. i tot that the best nitrate level is 0?? no??----------------

anyway yes, i deduced it from the chart.
i fear it might be lack of lights as the plants grow very fast, touchin the surface in only 4days.. so coverin the other leaves??..

That is NO2 (Nitrite) reading that you have. It is NO3 (Nitrate) that plants use. NO2 is a intermediate by-product when nitrifying bacteria convert NH3(ammonia)/NH4(ammonium) to NO2 then to NO3.
OUTLAW, why not you share your fertilising regime?
I remembered that you have had extremely high lighting. Why not you cut to 1x55W for the time being? I think the overly high light is driving your plants to consume nutrients too fast. K (potassium) deficiency is one of the prime suspect if you are not dosing it.
If possible, test for NO3 (not NO2) & PO4 (phosphate). These are 2 important macronutrients together with K that will determine the health of your plants.

Okay, will take the e advice.
Anyway do i remove these plants or ??

Most of the time the plants will recover if your solve the nutrient problems.
