Welcher Mangel ist das?

Galko420started grow question 1y ago

For about 10 days now, I've noticed that my leaves are getting brown spots. Unfortunately, these are becoming more and larger. Can I still actively counteract this? Furthermore, I see small white dots on the leaf surface. Are those salts?

Solved

Leaves. Curl down

Leaves. White powder

Leaves. Color - Dark-brown

Your plants definitely have a calcium deficiency. You can manage this well by using a CalMag supplement. If you're growing organically, the only option is really CalMag from BioBizz – at least that's what I use and I've had good experiences with it. In the developmental stage your plants are currently in, I usually use 1.5 to 2.0 milliliters per liter of watering water. This refers to using osmosis water, which is very low in minerals. If you’re using regular tap water, you would need to adjust the dosage accordingly – ideally based on your water values (e.g., EC value). Only then can you ensure that your plants are not over- or under-fed.

Brown spots on leaves that are spreading could be caused by several factors: Fungal or bacterial infection (like leaf spot disease) Inconsistent watering or underwatering Nutrient deficiencies, especially potassium or magnesium Sunburn, if the plant is exposed to direct sunlight White spots on the leaf surface could indicate: Salt deposits from hard tap water, often seen as dry white crusts Pest infestation, like spider mites or thrips, which can cause tiny white or silvery dots (check for webbing too) Powdery mildew, a fungal issue that appears as white patches

Hey growmie, Du hast definitiv einen Kalzium Mangel. Kommt extrem oft vor, wenn man unter LEDs growt. Gib den Ladys beim gießen bisschen CalMag, dann sollte es sich fangen. In folgendem Link kannst es auch nochmal nachlesen 👊 https://dutch-passion.com/de/blog/blattseptoria-vs-kalziummangel-n1109 Ich hoffe ich konnte dir damit helfen. Viel Erfolg im weiteren Verlauf 👊🍀
