Micro-mix Solution

Hello,

I am trying to copy Burr740's Micro-mix v11.15 (Sorry for that ) but with a small change.
Net water volume in my tank is 445L (Tank+Sump) with densely packed stem nutrient hoggers, ~170 PAR at substrate level.

CURRENT water parameters and dosing regime:

100% RO water
KH: 0
GH: ~ 3-4 dGH (I add CaSO4+MgSO4)
pH: 6.8

Weekly front loaded dosing

Nitrate 36 ppm
Phosphate 12 ppm
Potassium 48 ppm
CSM+B EI daily

weekly i do 35% water change.

I am trying to make Burr's MicroMix with:

Fe with DTPA Iron 11%
B - H3BO3
Mo - Sodium Molybdate
Ni- Nickel Sulphate 22%
Zn - EDTA Zn 12%
Cu - EDTA Cu 12%
Mn - EDTA Mn 12%
I've planned to add Cobalt as well, with Cobalt Sulphate 20%.

Values of fertz i estimated to make a solution mix (1000 ml Solution with 30 ml Per Dose) as follows:

Daily Dosing
Fe - 20.23g .15 ppm
B - 2.71g .032 ppm
Mn - 8.566g .07 ppm
Zn - 6.118g .0.5 ppm
Cu - 244 mg .002 ppm
Mo - 49 mg .0013 ppm
Ni - 33.37 mg .0005 ppm
Co - 36 mg .0005 ppm

Will it be OK if i replace my CSM+B dosing with this micromix? Is it going to harm my Plants and Shrimps as i do less than 50% water change weekly !! Please do note I have 0 dKH and very soft water as i mentioned earlier 3-4 dGH

 

I forgot to mention that i do Monthly 70-75% as well ... Like .. Let me put it like this (1Month) 35%-35%-35%-70%. This is just because i try to minimize the wastage of water as im living in a very dry place.

And secondly i tried that 3ppm Phosphate weekly butbyou probably wont believe. 3 weeks age when i figured out my tank is low on Phosphates (stunted tops, GSA, brown lower leaves) i done a major 70% WC and front loaded 12 ppm. On the 8th day(skipped WC to test how long my current dosing last) pearling almost reduced to less than 50% of the usual.. And from 11th day the lower leaf browning started again. And all this while i just dosed 0.05 pm IRON daily and nothing else. And that Iron was from EDDHA ... So not e than no other micros were added.

12th day again 70% WC AND front loaded all the Macros .... And things are all normal now pearlings are happening as usual, except a few plants like AR Mini, Ammannia Gracilis and Senegalensis ... It seems they aren't liking rest of the Micros except the Iron. May be because of the Root tabs beneath.
