Hyproponics The first thing to do is to prepare a check list covering such items as light, air, moisture in the aggregate, fumes, situation, hygiene and other significant points. Go through this, noting any likely causes. Light deficiency can give rise to poor blooms, weak stems, often elongated, and very pale leaves—a condition known as chlorosis. Sudden collapse may be caused by noxious gases or smoke and fumes. The leaves are excellent indicators of a plant's state of health. Leaf drop can be started by several things—overwatering, too dry an aggregate, or very sudden changes in temperature are some of the reasons for this trouble. Yellow or drooping leaves are frequently traceable to an excessively wet growing medium, with the drainage holes not being opened regularly or failure to feed properly with nutrient solution. Black leaves are dead, and frost and sun scald may be the culprits, while browning of the tips often arises from overfeeding (that is, not using the correct amounts of the nutrient formula in the water), exposure to draughts, and possibly too much liquid standing around the crown of the plant where roots and stem join. Leaf spotting is commonly ascribed to sun scald or watering from above in strong sunshine. Rotted stems come from too wet roots and over-application of solution. Stunted growth with small leaves, a halt in development and lack of bloom on flowering plants can be attributed to inadequate nutrition and light, or failure to look after particular needs of different types of plants. A common cause of trouble with household plants is lack of humidity in the atmosphere.
