To buy a seed is to believe in tomorrow

Are you a hobby grower or a professional grower then you definitely recognize this problem. Discolored sheets, aphids you name it.
The most important thing with leaf problems is to make the right diagnosis. If you don’t know what’s wrong, you don’t know what to do either. This can also be a cause and effect problem of an action that you have performed yourself. Below some options that can cause problems:
– Incorrect PH or EC value
– Change of food or food amount
– Aphid
– Change of pot
– Temperature
You see that there is a leaf problem and you are therefore investigating. You start by checking your pH value. A neutral pH value is 7. To be able to measure this properly, take a glass with pH neutral water. So acid it until it has a PH value of 7 before you start measuring! Add a tablespoon of soil and stir it briefly. After approximately 30 minutes, measure the water with a well-calibrated PH meter to determine a good pH value of the soil. Is the value incorrect? Then gradually compile this with feed water until it is in order again.
Have you changed your diet last year or have you started to give more food? Then check your feeding schedule carefully to see if you don’t give too much. If the pH value is in order and the problem is not resolved, the plant is expected to receive too much nutrition. You often see a yellowed color on the tips of the leaves. Dotted leaves and the loss of a leaf is also a result of too much nutrition. This often causes a backlog of growth, and therefore a lower yield.
Do your leaves curl or roll up? Then the temperature is expected to be the problem. This may be due to a large difference between day and night. If it is not pleasant for you in the grow room, then that is often also the case for the plant.
Here is a short list of generally recommended temperatures.
Without CO2 addition: 21 – 26.5ºC, with CO2 addition: 26.5 – 32ºC,
in the last two weeks of the flowering period with low CO2 addition:
21 – 26.5ºC. At night: at least above 15ºC.
And for the feed water: 23ºC.
