Brown spots on lowest leaves

Cawabungastarted grow question 10 months ago

Hallo Freunde! Ich habe an den untersten Blättern meiner Pflanzen, Verfärbungen auf der Blattoberseite entdeckt. 😲 Ich vermute das etwas Überdüngung die Ursache ist. Week 3 Day 19 Wenn jemand die genaue Ursache und wie ich es behebe, erklären könnte? Vielen Dank 😗 Cawabunga 💤

Nein, der tritt überall an der Pflanze auf. Aber für einen Kalziummangel ist mir das eigentlich zu gleichmäßig zwischen den Blattadern. Das ist eigentlich eher typisch für einen Magnesiummangel, würde aber mit hellen Verfärbungen einher gehen. Ich tippe auf einen besonders schönen Kalziummangel mit angehendem Magnesiummangel. Das müsste dann eigentlich auch recht schnell voranschreiten. Spüle die Pflanze mit PH und 20 Prozent Abfluss. Danach mit PH und leicht gedüngtem Wasser inklusive einer leichten Dosis CalMag angießen. Dann sollte es ihr schnell wieder besser gehen. Wenn du da hast, oder schnell herankommst... du kannst ein halbes Gramm Epsomsalz mit einem Liter Wasser mischen und die Blätter damit besprühen. Das gibt ihr wieder Magnesium. Happy Gardening 💪😎

@Terp1 Vielen Dank, ich habe mich an deinen Rat gehalten und keine weiteren Probleme mehr gehabt. CalMag hat geholfen!

@ Terp1 Ok das werde ich mal versuchen. Ich habe die Pflanze einen Tag nachdem die ersten Flecken auftraten umgetopft. Also nicht aufgrund der Flecken, ich wollte an diesem Tag sowieso umtopfen. Die neue Erde ist LightMix von Biobizz und ist bisher nicht gedüngt worden. Sollte ich trotzdem spülen oder könnte das evtl. schon geholfen haben? Danke schonmal! Gruß

Wäre ein Kalziummangel nicht zuerst an den neuesten Blättern sichtbar? Betroffen sind allerdings nur die untersten ältesten Blätter. Gruß Cawabunga

I think this brow spots are calcium def. Make a foliar spray with callmag. 10ml/l. Make this with lights off, to avoid burn. My OGs aways ask for call Mag, i aways do foliar during the vegetative stage. Helps a Lot.

Tache cuivrés sur feuille.Je me demande si les tâches cuivrées sur les feuilles de ma plante de cannabis et d'autres plantes sont dues à une carence en calcium ou en phosphore/potassium. Les feuilles affectées sont généralement les grandes feuilles, souvent nourricières. Voir agenda. Je vous remercie 🙏🌱

What is causing this Leaf discolouration overnight after a lot of tent work yesterday Spent a lot of time in the tent yesterday. Everything was fine and this morning there’s bad discolouration on the leaves of some plants. I did lower the plant (was way too high) so may beight burn - but it’s only on some plants I did make two mixes of water/nutes
