Let me start of by saying that I am a person with very little experience of gardening. I have just been growing some plants in my balcony and in the process fell in love with this hobby and stumbled upon Hydroponic gardening. Since then I have been reading a lot about hydroponics but one thing has been confusing me and I would like someone to clear confusion revolving around nutrients.
I understand that all the nutrients that plants need in hydroponics are provided through water. I am not clear about the following things:
Should I use normal hydroponic nutrient (sold in two parts A & B) or should I use so called hydroponic fertilizers.
If I start with A & B Nutrients, should I replace them with fertilizer at the later stage when plant starts producing flower, should I mix them both or will simple nutrient formula be enough for the plant?
Can I use ordinary soil fertilizer, for hydroponics and save some money or will it not be enough?
I know the question of nutrient will depend heavily on the plant under discussion so I am taking chilli peppers and tomatoes for reference.
