Seachem Flourish vs Plantex CSM+B

I was searching this form and reading up on PPS-PRO. I noticed that Flourish and Plantex CSM+B have mostly the same ingredients but the Seachem product appears to have much less strength. The following chart is from a 2011 post on this board:

CSM+B Plantex
Guaranteed Analysis:

Total magnesium - water soluble chelated magnesium 1.5%
Copper - chelated 0.1%
Iron - chelated 7.0%
Manganese - chelated 2.0%
Molybdenum 0.06%
Zinc - chelated 0.40%
Boron 0.04%
EDTA - minimum content 55%

Seachem's Flourish
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%

----Am I correct in thinking that Plantex is 10 to 100 times stronger in potency than the Flourish? If so, there is no way that I can use the Flourish for the micros in the PPS- PRO formula? Correct?

I don't know much about pps-pro since I use EI dosing. But yes dry fertilizers are much much stronger than what you get in the premixed fertilizers in the petstores. But you can dilute it to the strength you want, so I see no reason you could not use it.

You can use a converter like this one to see how much Flourish Comp you'd need for PPS, EI, etc.
