Nutrient deficiency causing hibiscus yellow leaves
If your hibiscus is suffering from a nutrient deficiency, the leaves will turn partially yellow but remain on the plant. This can be easily corrected by adding fertilizer or amending the soil.
Nutrient Deficiency
If soil drains well, has ample water, is neither too acid nor too alkaline, yet still fails to sustain plant growth well, it may be deficient in nutrients - most likely nitrogen.
Organic Matter ...
#2. Nutrient Deficiency
Lawns lacking in nutrients will develop a sickly yellow look. If you haven't fed your lawn in a while, you should suspect this culprit. The lawn care solution is a bag of fertilizer.
Nutrient Deficiency Symptoms
The amount of fertilizer to apply to a garden depends on the natural fertility of the soil, the amount of organic matter present, the type of fertilizer used, and the crop being grown.
Some plants are fussier than others, but if the soil pH is too acidic or alkaline, the plant will not be able to take in nutrients no matter how rich your soil may be.
Plant Nutrient Deficiency Symptoms ...
Solid organic fertilizers are another option when vegetable plants show signs of nutrient deficiency. Choose well-rotted or composted manures, blood meal or manure-fortified composts of decomposed plant matter.
Off-color foliage can be caused by a nutrient deficiency. If the color is paler than normal, it may indicate a nitrogen deficiency. If the leaf veins are green but the area between them is yellow, suspect an iron deficiency.
Potting soils generally lack nutrients essential for plant growth, but a regular fertilization program will compensate for this nutrient deficiency.
If the test results indicate a nutrient deficiency--say of nitrogen, phosphorous or potassium or perhaps even iron--take the necessary steps to correct it using a natural fertilizer.
Two good rules of thumb are to mulch with 3 to 4 inches of bark mulch each season and to avoid mulch layer buildup (and potential nutrient deficiency problems) by removing old layers of undecomposed mulch before adding new layers.
Chlorosis: Yellowing of the leaves caused by a nutrient deficiency, lack of light, light that is too bright, or high temperatures.
Companion Planting: Growing plants together, or in close proximity, for their mutual benefit.
Iron is the most common micro-nutrient deficiency in alkaline soils. Iron deficiency is known as chlorosis. It is typified by yellow leaf margins between veins and in severe cases, leaves may wither and die.
Removing needles annually from underneath evergreens may eventually cause nutrient deficiency in evergreens.

Controls weeds effectively ...
Older trees are usually more susceptible to the disease, but any tree can succumb if it is stressed, for example by drought or nutrient deficiency.
Chlorosis - the condition of a sick plant with yellowing leaves due to inadequate formation of chlorophyll; Chlorosis is caused by a nutrient deficiency, usually iron or imbalanced pH.
Circuit - a circular route traveled by electricity.
During their long, hot growing season, they suffer from the ravages of wind, insect and disease pressure as well as from other conditions such as nutrient deficiency and lack of pollinating insects.
If the weeds look unhealthy, then the soil there may have a nutrient deficiency. Crabgrass, plantains, sheep sorrel, and horsetails prefer acidic soil, while chamomile and goosefoot like alkaline soil.
Some symptoms are almost always going to be abiotic, such as leaves that are yellow-green color (low nitrogen, excessive moisture, planted too deep); yellow leaves with green veins most likely means nutrient deficiency or drought; ...

Nutrient deficiency (yellowing of leaves) is most often caused by a lack of manganese or injury from weed killers.
Aphids can cause leaf drop and fungal infection. You can use horticultural oil or insecticides as soon as any damage is visible.
