Welcher Mangel ist das?

Galko420started grow question 23d ago

Seit etwa 10 Tagen zeichnet sich ab, dass meine Blätter braune Flecken bekommen. Diese werden leider immer mehr und größer. Kann ich jetzt noch aktiv gegensteuern? Des Weiteren erkenne ich kleine weiße Punkte auf der blattoberfläche. Sind das Salze?

Bei deinen Pflanzen liegt auf jeden Fall ein Kalziummangel vor. Das kannst du gut in den Griff bekommen, indem du einen CalMag-Zusatz verwendest. Wenn du biologisch anbaust, kommt eigentlich nur das CalMag von BioBizz infrage – zumindest arbeite ich selbst damit und habe gute Erfahrungen gemacht. In dem Entwicklungsstadium, in dem sich deine Pflanzen gerade befinden, verwende ich in der Regel 1,5 bis 2,0 Milliliter pro Liter Gießwasser. Das bezieht sich auf den Einsatz mit Osmosewasser, also sehr mineralarmem Wasser. Solltest du normales Leitungswasser verwenden, müsstest du die Dosierung entsprechend anpassen – idealerweise auf Basis deiner Wasserwerte (z. B. EC-Wert). Nur so kannst du sicherstellen, dass deine Pflanzen nicht über- oder unterversorgt werden.

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 👊🍀

Leaves are gray/brown and curl down. HELP!Im a first time grower and I cannot figure what’s wrong. I’ve been feeding it Calmag and Grow from Biobizz since last week. 1 ml/l grow, 0,8ml/l calmag. PH of water + nutes is 6.3. The soil is coco and pearlite. Did I give it too many nutrients? Did I overwatater?

Leaf damage/discolouration The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

Wind burn or over water?The leaves on my plants are getting a little crooked. Look at the last photos in week 3 to see. My fan is in low pointing away from the plants. The little guys move around a little bit, but I’m worried it’s too much. Or am I overwatering? If look, you’ll see I don’t wander much.
