Burning from over feeding. Nothing to do with calcium. 18/6 is best for cannabis, they NEED sleep.

Should I be worried with yellow and brown tipped leaves? Will it affect quality or yield? Can I correct this? With my nutes I used sturdy stalk and Ph’d water 6.3 and I feel it could be the lights but it also started from over feeding Nutes. B4RNS called it!

What is causing this on the leaves? I'm not sure what I am doing wrong. Is it possible the heat and humidity are too high? Humidity up to 77% and can't seem to get her down sometimes. Heat is around 27/30 degrees during light hrs. Did I fuck up the transplant or grow conditions?

Many or low nutrients?
Hello Growers What could it be? I thought it would be a nutrient deficiency (EC-1.0) so I picked up the nutrients to EC-1.4, but it's getting worse. Do you think they'd have a lot of nutrients?

First grow, calcium deficiency?
First grow, help please. As seen on the pictures provided, the leaves are getting brown spots on them with some kind of yellowing. I also do have some yellowing tips. I do suspect a calcium def. after some reading but would highly appreciate the input of a more experienced grower

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.
What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Black spots?
Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.

The plants get yellow leaves
Guten Abend ich bin hier neu, und habe folgende Frage; meine 4 Francos Lemon Cheeses werden immer hellgrüner? Sie stehen in einem 50x100cm Zelt und werden von einem Zeus XT 308 in der Farbe 3500K Cri 90 beleuchtet. Die Erde habe ich aus ca. einem Drittel gebrauchter Erde und 2 Drittel Plagron All Mix gemischt, und je 2 BioTabs/Topf gegeben. Stehen tun sie in 11l Pflanzensäcken. Seit einer Woche wird eine extrem hell und später werden die Blattränder braun, aber jetzt werden alle heller und sehen nicht mehr gesund aus. Laut meinen Recherchen schauen sie unterdüngt aus, aber ich bin mir absolut nicht sicher. Vorgestern war Gießtag und ich habe folgendes dem abgestandenen Leitungswasser beigemengt. 3ml/l CalMag von Biobizz 5 ml/l Melasse und 5ml/l Bio Tabs Orgatrex sowie 2ml/l Terra Grow von Plagron. Vor ca. 10 Tagen habe ich zum ersten mal gedüngt und habe ca. 5ml/l Bio Tabs Orgatrex und ein wenig Melasse gegeben und vor 6 Tagen habe ich geflimmt. Die Pflanzen sind etwas über 5 Wochen alt. Ich bin auf Eure Tipps gespannt und sag schon mal danke.
