Nutrient Usage Issue

One quick question. Iâ??m using Miracle Grow right now and the instructions say 1 tsp for every 4 litres INDOOR or tablespoon for every 6litres OUTDOOR, etc. What exactly does this mean? What is the standard you growers use for indoor, the indoor solution or the outdoor solution?

For instance if the indoor use is 1tsp for 4 litres of water, I mix it up and then put some of the water into a bottle. Do I feed the nutrients every time I water the plants with the solution or once every week until the jug is empty. Additionally, how much IS a serving for the plant, a tablespoon near the plant or 25ml, etcâ?¦?

Iâ??m rather puzzled since I bought one of those bins of miracle grow and thereâ??s no possible way to run thru a package, even in a year! Iâ??m sure I am doing something wrong, can any1 enlighten me?

Thanks
