Advice Needed : Which nutrient solution to use for terrace hydroponic farming

Hello all,

I’ve recently built a NFT hydroponic system at home for experiment and have been looking for the right nutrient solution need for the same.
Recently, I have found the following two :

  1. RHBP Bio fertilizer containing 16 Macro & Micro nutrients
  2. RHBP Jeevan Jal Growth promoter containing 14 Nutrients

But I do not understand which one is more optimum. Should I go for Bio fertilizers or Growth promoters?
Also, please suggest any nutrient solution that you may know of.
