A plant can be stressed when it desires nutrients but can not get any. With hydroponic techniques, plants are never stressed. Air, nutrients, and sunlight are always available to the plants with a hydroponic setup. Sunlight is readily available when the garden is located outdoors; however, when a garden is indoors artificial lights can be set up to simulate natural sunlight. Sufficient air circulation needs to be setup for indoor setups as well or the roots may die. With a good air circulation setup, the air may also prevent any disease which may be caused by conditions which are too moist.

Remove dead leaves to better spread nutrition within the plant. Also if the rest of the plant is healthy it may will be an infection or some sort of disease. It is important to study all your plants carefully, if any plants have symptoms of infections remove them immediately to prevent any bacteria from spreading. Before introducing a plant in the previous diseased area, clean up any residue left behind. Diseased Plants should be removed and its area should be cleaned thoroughly with a bleach solution. Before changing any water in the tank, wash it out with a cleaning solution. Remove any residue, and make sure areas which hosted a diseased plant are cleaned properly.

The nutrient concentration of a hydroponic garden is often referred to as the EC level. If your hydroponic garden consists of Grodan plants, they would require less fertilizer then what they would need in a soil based garden. This is because of the technical system of hydroponic gardens. In soil gardens the nutrients in fertilizers are not all absorbed by the plants, because the soil acts like a buffer.
