Hi Ashok kumar.
The only difference between a lab grade and agricultural grade fertilizer is the amount of impurities in it.
lab grades are much more pure than the agricultural grade, But for our application I feel its not much of a issue.
I too dose with agricultural grade fertilizer and the plants are doing fine.
Only concern is with the rexolin cxk micro nutrients, The micro fertilizer can be tricky as a slight increase / decrease in any one element can trigger a deficiency or toxicity in plants and has the potential to harm the inhabitant animals. I would suggest you to go with CSM-B for micro nutrient.
all other fertilizer can be used as per recommended recipes Like EI, PMDD or PPS Pro..
No matter which recipe you follow you may have to modify the recipe according to your specific tank. because your tank is unique and nobody can give a standard recipe which will work on all tanks.
The link below is a calculator which can help to calculate the fertilizer dosing.
