    Dear all

    I had a quick question on how to use the additives we have to add for the plants nutrients.

    The question is with regards to plant nutrients additives we add for Calcium Potassium and Magnesium.

    1 Option that was told in Murray's class was to add 1 table spoon of calcium carbonate slurry for 1000 liter of FT water when ever the PH is down and every 4th time we make a buffer of potassium bicarbonate slurry.

    2nd option which was told was using 40:20:10 gram ratio of calcium carbonate, potassium bicarbonate, magnesium sulphate respectively for 2000 liter FT water. But not sure when to use this and its frequency. Kindly suggest me how often to use this and the frequency.

    kindly advice which option to follow. or have to use both methods ?
