EI dosing 40g

I've been dosing 1/8 tsp of KH2PO4, 1/2 tsp of KNO3, and 1/8 tsp of CSM+B. My question is, is this too much? I checked on the wets calculator and according to that it is. I felt like I needed to dose more npk since my ludwigia glandulosa leaves don't look to good. Also should I be dosing GH booster if using tap water? My tap has a GH of 10-11 so should I just dose magnesium? TIA,

First is that a once a week dose ?
Your GH seems good (or a tad high)so why dose any GH booster.
I hope you are at least doing a 50% weekly water change because the KH2PO4 is double normal from what I've heard on here.
CSM+B sounds normal.
KNO3 seems not enough but this is often cut in half or fourths and K2SO4 substituted for the remainder to help lower nitrates.
So you are way over in KKH2PO4 but under in the KNO3.
But this is IF this is a once a week dose.
But I'm also basing it on the "EI Low light/Weekly" doses and not very exact either as I did mine a while back and haven't checked it lately and
I have a 10g and I'm just multiplying it by four.
In the fert section is suggested list for various size tanks in the first thread.
Why don't you just use only one dose of that. It's a three dose schedual.
But it's for high light/injected CO2 tanks.

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

I dose 3 times on alternate days with a 50% WC on the 7th day. I was told by another that I was lacking macro nutrients is why I asked and had a hair algae problem. Thanks for the info though.

Bump: I am dosing according to the 40-60gal requirements on the post you mentioned.

Bump: Guess I should have stated that its a high light co2 injected tank.
