Still, less light is the best method to reduce the rates of growth, thereby the demand for CO2, and thereby the demand for nutrients.
You do not wag the dog by the tail, the tail is "wug" by the dog.
So start with light, then reduce it.
This way you have much more wiggle room with dosing no matter how you go about it.
I'd also suggest using soil/ADA As etc. This will give a back up if you go too lean with the water column dosing.
Then you have hedged the bets much better with light+ sediment macro ferts. Now dosing should be very easy and management and growth rates easier, but you can still keep most every species you want in excellent shape.
I'd say you can easily get away with 1x a month water change at 30-40micro light+ sediment ferts, + light water column dosing.
This is a holistic approach, you start with light, then go from there.
That is where all algae growth and plant growth starts, not with nutrients.
Many seem to poo poo EI and focus on the nutrients, without giving hardly any consideration to light, measuring it, adjusting it etc.
EI is just a tool that uses water changes and does not imply high light. I've used EI on low light tanks without any issue and gone a month without water changes. I do not need to dose, but doing so caused no harm that I, others, have ever demonstrated.
But common sense should be obvious/prevail here, with lower light, lower growth rates, obviously anyone with 1/2 a brain would predict less uptake.
So dose less.
These nutrient dosing, sediments etc are not strict dosing methods.
If they where, few would be able to master them. You can and should modify to suit. I use rich sediment and dose similar EI levels with high light, and maybe 1/2 or so with low light. I dose traces richer still, but it's not mattered either way, it's just adding enough for the plants for the most part.
I just use the light intensity to change the rates of growth to make things easier for myself. Much easier all the way around, cures most any algae issue, makes CO2 easier etc. If I leave for a few days, week or two, I adjust the light up and bit and the sediments provide some back up while I'm gone.
