Leaves that are burnt and lighter in color are very common issue. Most common cause: pH too high or too low.

Because a pH in a medium, for example, falls below 5.2 or above 6.0, it happens  that many different salts can no longer be absorbed by the plant. The greater the deviation from the ideal pH, the less the absorption. The plant gets a shortage and becomes lighter in color. However, all this time, they have given feeding sessions, reducing the concentration of dietary salts has accumulated more and more. Eventually one gets too large an Osmosis imbalance, which will be compensated by withdrawing water from the leaf back into the medium. This phenomenon is also called leaf burning (burning leaves).

A first warning for burnt leaves is often the curling up or the edge of the leaf. The plant notices the balance difference with the medium and is the first reaction to close the stomata on the outside of the underside of the leaf.

A common problem with indoor cultivation is that the fruit onset becomes harder, but does not want to grow. Growers spend a power on extraction and ventilation equipment, but sometimes forget that what goes out must also come in again. Most of the time they have a too small blower against the suction or no blow at all but a small opening somewhere below. In this way you create too much underpressure and the plants crave fresh air (CO2). If the door were to be left ajar for a week, the plants would become almost twice as large after this week. Simply having the right capacity blown in or a much larger inlet hole is best for this problem.

Shortages, heat.

Growers sometimes have the fact that they are growing volume with little content. This usually occurs in climates where the temperature around the leaf is 32 ° C or higher or the light is very poor. The plant grows outward, as it were ...

If the temperature is too high, simply bring the temperature down or allow the plant to cool more by lowering the Ec. When the plant is too hot, it wants to cool more. The plant does this by evaporating more water. However, if this is not possible because the medium is too dry or there is too much nutrient in the medium, the plant will create surface to be able to cool in this way. The best solution for this is to reduce the Ec by half by heat. The plant will then drink a lot more and evaporate to cool down and still get its amount of nutrition.

This also depends on the genetics of the plant, of course, one plant is more sensitive than the other. If the pH is good and the EC for watering is quite low, you can raise the EC of the water gifts.

Even if dietary intake is somehow stagnated or the plant simply needs more than is present, the plant can increase in volume.

Many growers who often see that the sides of their leaves usually go up at the top shavings. Metrop Stomata with which the plants breathe are at the bottom of the leaf. For the absorption of nutrients and water, these stomata must leave water evaporate. However, if there is a malfunction that causes a plant to evaporate less water than close the plant some of these stomata on the outside of the leaf. You will then see the leaf edge curl slightly. The greater the disturbance, the more stomata close and the farther the leaf curls up. The causes of the malfunctions can be:

1. Too large evaporation under the leaf. If by heat, low humidity or a fan that is too hard on the plant state can be the plant evaporate more than he can absorb.
2. Too many salts in the medium by means of overfeeding or the wrong pH. The medium then wants the imbalance of salts in the plant and outside of it plant (medium) compensate by retaining water, or even withdrawing from it leaf (leaf burning). The leaf then receives little or no new moisture and no new moisture it closes the stomata.
3. An air shortage in the medium makes it difficult to move elements. Curly leaves are always an indication for the grower to take action to undertake.
