Damaged fan leaves
OGgrowsanswered grow question 6y ago
Hi @NanoGrows The burns on the leaves seem to me to be PH variations. It regulates the PH of all waterings to PH 6. The discoloration between the leaf veins seems to me to be a calcium deficiency. good luck mate 👍

Looks like over watering to me. There are speed bumps and yellowing vanes on leaves.

yellow/copper appearance in some leaves after first run off wateringhi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints .
this is only on old leaves so looks like mobile nutrients.
could this be cal-mag issues?4y ago

Light green "splotches" on leavesHi,
I've noticed light green "splotches" on my leaves which I'm having trouble matching with images of leave problems. Doesn't appear to be impacting on growth and the issue is only visible on close-up so it might just be me being over concerned, but I'd be grateful for advice!Week 2

Iron deficiency?This A.M I treated her with a cal-mag mix due to yellow leaves. Today the leaf showing symptoms "tacoed" a little bit and the tip curled upwards. Same symptom on a few other leaves but only on the tips. Iron deficiency perhaps? PH'd soil on 3 spots: 6.6, 6.18, 6.3. What to do????Week 5

Do my girls look healthy? There's small lighter green patches here and there and some leaf curl. I might be a over analyzing/reacting. I'm a little paranoid but autos supposed to be finicky and stunt easily, and can go from bad to worse very quickly, from everything I've read.ThxWeek 3

Their appears to be little brow spots/specs scattered on the fan leaves, I feel like I’ve seen it before but completely forgot what it was so if anyone knows if it’s a deficiency of any kind it would be appreciated. I ruled out nute burn because only one out of four has it.Week 2

The plants get yellow leavesGuten 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.Leaves. Color - Yellow

Hello,
There are copper coloured spots on many leaves on one plant. I have tried Foliar spraying with magnesium. But it doesn’t seem to help. There is a bit of purple in the stems as well. I gave them some cal-mag, but still there. A few fungus nats. Gave nematodes 2 days ago.Week 11

Leaves looking a bit discoloured and wilting slightly, what could be causing it?Leaves are drooping a bit and slightly discoloured, especially when comparing it to the other plant. Also, a couple seem to be growing at a much slower rate, is this anything to worry about or will they catch up? TIA5y ago
