I have started hydroponic gardening for last three months in India . I am using both dutch bucket and NFT , both seperately. I am facing frequent pH change problem, I.e, it is going high everytime. I need some advice.

Welcome to the forum!
I use deepwater systems, and I have the exact opposite thing happen - the pH drops eventually. I don't change the water - I just add some potassium bicarbonate, which brings the pH up, plus adds some K to the solution. A friend who had very high pH local water used a commercial "pH down" powder, which had phosphoric acid in it.
