Hoppy - lol im always dizzy by the time i get done reading about this stuff... and i thought i understood until you went and said that :P I knew gh booster had mg in it. And I have very little NO3 so definitely need to dose that. But I thought I was already adding Mg with csm + b. Plus it comes compliments of the hard water. and its in flourish.. (i am bound and determined not to waste that bottle of flourish)
From my notes:
Macro: Carbon (C), Oxygen (O), Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg) and Sulphur (S)
Micro: Iron (Fe), Manganese (Mn), Zink (Zn), Copper (Cu), Boron (B), Nickel (Ni), Chlorine (Cl) and Molybdenum (Mo)
Mon: KNO3, KH2PO4, K2SO4
Wed: KNO3, KH2PO4, K2SO4
Fri: prune, clean glass, 50% WC, add KNO3 & Flourish
Trace in my case being:
Plantex CSM + B = 1.50% Magnesium, .10% chelated copper, 7.0% chelated iron, 2.0 manganese, 0.06% molybdenum, 0.40% zinc, 0.04% boron
K2SO4 = potassium sulfate (which has sulfur)
Hard water = calcium carbonates and magnesium
Flourish Comp = Total Nitrogen 0.07%, Available Phosphate ( P2O5) 0.01%, Soluble Potash 0.37%, Calcium (Ca) 0.14%, Magnesium (Mg) 0.11%, Sulfur (S) 0.2773%, Boron (B) 0.009%, Chlorine (Cl) 1.15, Cobalt (Co) 0.0004%, Copper (Cu) 0.0001%, Iron (Fe) 0.32%, Manganese (Mn) 0.0118%, Molybdenum (Mo) 0.0009%, Sodium (Na) 0.13%, Zinc (Zn) 0.0007%
Barrs GH booster = 1 part magnesium sulfate, 3 parts potassium sulfate and 3 parts calcium sulfate
But I'm already adding those things several times a week to already hard water, so I didn't think I needed it?? Esp. since I don't have very high light and i have relatively low CO2.
that the aforementioned regime with my already hard water would allow me to check everything off of of the nutrient list.... except Nickel... which is probably in the tap anyway... at this point, f*&% the nickel.
Don't over think it! I only say that because I did and I later learned it's really pretty easy!
