Planted tank starter?

[ancientfins]

its almost 3 months in running, started it likely dec 26 last year, it was all subulata at the start just added the hygro and indica after a month, the indica is growing well right now, ill be setting up soon a bigger tank, just waiting to pick up some dwarf hair grass,

The more light, the more the plants photosynthesize.
The more the plants photosynthesize the more demand they have for Carbon (co2) and Nutrients (nitrates, phosphates, potassium, Iron + trace elements)

Since algae is also stimulated, but NOT limited by the need for all those nutrients, herein lies the problem and the need for a balance.

I still don't get it.
I'm not saying you're wrong, but according to this if I have 2 exact set up planted tanks without any ferts (just fish waste) the one with lower light will give better growth than the one with high light. I just can't seem to see it that way.

Here's something HarleyK said in his thread "Debunked: CO2-Myth --- See tanks without carbon dioxide fertilization"

"There is science behind it: Liebig's Law. The one nutrient/factor that a plant is short of, limits growth - even if all other factors/nutrients are overabundant. That one factor is most often quality light, followed by minerals (iron+trace elements). In only very few aquariums you will find that CO2 is that bottleneck. Believe it or not, in my 220 gal, that one limiting factor is nitrate."

and that makes sense to me.
