Based on the data that I have, the reason I believe that I've only had good results, not great results, using foliage pro in hydro for flowering is not because of the cal and mg content (or the N to Ca ratio), but because of the NPK ratio of fp. You can run elevated levels of calcium and magnesium in your reservoirs if you want but I know for a fact that a lot of that is going into the sewer at your res change. Like I said before, just because it's in your res doesn't mean your plants are using it.I agree about the micro nutrient level however I believe the macro nutrient levels ie calcium and magnesium are way to low to be optimum particularly for hydroponics. Commercial hydroponic
farmers always run much higher cal and mag. A 4.5 to 1 nitrogen to calcium ratio is not
good in my opinion.
Now if you're saying there is proportionately too much N in foliage pro as compared to P and K, then I might agree with you there.
