ppm list of nutrients

Asked a million times no doubt, but a link to a list of target ppm of
the nutrients your tank/plants need please...

The shortest distance between any two points is a straight line...in the opposite direction...

Is this what you need?

CO2 range 25-35ppm
NO3 range 5-30ppm (KNO3)
K+ range 10-30ppm (K2SO4 or GH booster)
PO4 range 1.0-3.0 ppm (KH2PO4)
Fe 0.2-0.5ppm or higher (?) (Plantex CSM +B)
GH range 3 degrees ~ 50ppm or higher (GH Booster)


You may find this post helpful, albeit long winded lol

I believe it was you who answered a question for me yesterday on ferts(in someone else's thread) about how to add values to get
total ppm as the calculator does each individually. And once I get the total from all of my ingredients I can use this to adjust to
the target ppm after they are all combined. My Macro list is just KNO3/KH2PO4/K2SO4 for now but I also want to cut it to 1/3rd
of the total target ppm to keep down on water change percents.
I would rather they get slightly less but of everything they need...

Consider using the EI low light/weekly dose listed in that calculator. That's about one third EI which seems about right for low tech which is essentially what you are applying it towards, correct?

When things are growing well and stable then you can slowly reduce nutrients until you see problems.

edit: Just read one of your posts. If you want to reduce growth rate "take your foot off of the gas" don't "water down the fuel". What that means is reduce your lighting to control growth rate in a low tech. Light drives nutrient uptake and plant growth. Nutrients should be the easiest of all oddly enough.

Yes that is pretty much what I'm doing, but when I added the low light EI suggested amounts in ppm they came to about 250% of the target ppm on one nutrient and I believe it was the K which target value I had so I asked for the rest of them.
That I think was fine for the first couple of doses as none existed before so they likely got used up quickly.
But I'd rather not keep up this rate of any that are that high.
Actually don't remember if it was in that thread but I also intend to cut my light by additional floating plants and drop the Excel after the plants
are more fully filed in and just more of them in general.
