I agree, check with the building engineers/structural surveyors for your building. The weight of a large container of soil, plus the water it will hold, plus a person or two on your balcony sounds like a recipe for disaster to me.
What's wrong with a few pots?
Otherwise you're just going to have to rent some garden land nearby or save up to move to a place with a garden.
