Nutrient Disorders

When the hyroponic garden is on a regular maintenance shedule and the gardener knows the crop will,nutrient problems are usually averted.If nutrient problems are usually averted.If nutrient deficiency or excess affects more than a few plants,check the irrigation fittings to ensure nutrient-challenged plants are receiving a full dose of nutrient solution.Next,check the substrate around affected plants to ensure nutrient solution is penetrating entire medium and all roots are wet.Check the root zone to ensure roots have not plugged drainage conduits and are not standing in stagnant solution vertical farming racks.

Hydroponic gardens have no soil to buffer the uptake of nutrients.This causes nutrient disorders to manifest as discolored foliage,slow growth,spoting,etc.,at a rapid rate.Novice gardeners must learn how to recognize nutrient problems in their early stages to avoid serious problems that cost valuable time for plants to recoup.Treatment for a nutrient deficiency or excess must be rapid and certain.But once treated,plants take several days to respond to the remedy.

Nutrient deficiency or excess diagnosis becomes difficult when two or more elements are deficient or in excess at the same time.Symptoms might not point directly at the cause.Solve mind-bending nutrient deficiency syndromes by changing the nutrient solution.Plants do not always need an accurate diagnosis when the nutrient solution is changed.

Overfertilization,once diagnosed,is easy to remedy.Drain the nutrient solution.Flush the system at least twice with fresh,dilute (5-10 percent) nutrient solution to remove any lingering sediment and salt buildup in the reservoir.Replace with properly mixed solution.

Nutrient disorders most often affect a plant variety at the same time it is receiving the nutrient solution.Different varieties may react differently to the same nutrient solution.Do not confuse other problems-windburn,lack of light,temperature stress,fungi and pest damage-with nutrient deficiencies.Such problems usually appear on individual plants that are most affected.For example,foliage next to a heat vent might show signs of heat scorch,while the rest of the garden looks healthy.Or a plant on the edge of the garden would be small and leggy because it receives less light.
