Hydroponic growing is a more technical skill than growing plants in soil
  3. The first signs of CO 2 toxicity are often mistaken for other problems and include leaf damage such as chlorosis (yellowing), necrosis (especially on tomatoes and cucumbers) and curling of leaves. Sometimes growth reductions and stunting caused by high CO 2 levels can occur with no other visible damage symptoms or injuries to the plants
  4. Hydroponic lettuce, and other similar leafy greens, are successiptable to a physiological disorder commonly called tip-burn. The disorder is related to a calcium deficiency at the tip of the leaves, but it is rarely actually caused by a lack of calcium in the nutrient solution


• American Hydroponics • FarmTek • Example Dimensions - 4 wide x 1.5 deep x 12 ft long. Ex: Automated systems with metal channels • Old leaves affected Crops • Head Lettuce. Outer leaf edge necrosis. Causes • Guttation (leakage of water and salts) at hydathodes • High RH (or fluctuating high RH nights, low RH days outer leaves. Tomato Spotted Wilt Virus Tomato Spotted Wilt Virus (TSWV) - numerous tiny spots on the younger leaves and stunted plants that fail to head and then begin to rot. Symptoms also include downward leaf curling and extensive necrosis. It takes one to two weeks to go from initial symptoms to plant collapse Cause: Even a few hours without water can slow a seedlings' growth and after a day the plant may begin to curl its leaves to conserve moisture. Hot grow lights and the dry air inside heated homes can rapidly dehydrate plants, too Look for signs like upward leaf curl, which indicates the leaf is trying to retain moisture. In this case, the light will probably be too close. Interestingly, plants can cope better with intense light in a hydro system, where there's lots of water and oxygen available. As long as your plant's fairly healthy and growing every day, all is well

Leafy greens such as lettuce, arugula, kale, mustard and spinach are among the most popular locally grown vegetables.

Sometimes lettuce just does that-- it has a little bit of stem before the leaves start. If that stem gets too long, it can bend over. Growing in dirt, I just mound the dirt (actually potting soil) up around it

Potassium: Older leaves develop marginal browning which can extend into the leaves, and forward curling of leaves. Calcium: Shoot tips yellow and die back, young shoots have abnormal growth with eventual die-back. New leaves affected first with distorted leaf growth; roots tips die back leaving short stubby roots with black spots Potassium - Not enough potassium in your hydroponic nutrients will create leaves that have edges that look blackened or burned.. They may also develop brown, dead spots. These signs typically show on the older leaves first. The fruits and flowers of a potassium deficient plant may also be lighter in weight than normal Lettuce Pest Control Tips.
