Magnesium deficiency You may need to raise the ph up a bit between 6.2-6.5 would be ideal This will allow all of the nutrients to be absorbed better

Leaves Showing yellow edges and banding
Is yellowing of leaves and dark leaves toxicity? no curling . moved the lights further away. I'm growing organic. The plants look stunted short dense. I've only got a cheap pH meter calibrated. 🤞 use RO water pH- citric acid. Overall they are short dense growth wise

Strange leaf deformation
Have these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol. Several leaves have this. Combined with a slightly general canoeing, could it be from a nitrogen tox ? Growing good though Cheers

Woran könnte es liegen ?
Nährstoffarmen oder zu wenig Wasser ? Die letzten 2 Wochen hat es überhaupt kein Tropfen geregnet und giese nur selten da wir ab so 30 cm Tiefe den Boden eigentlich feucht haben . Bei dem Wetter bin ich mir aber nicht sicher.

Heatlight stress?
Can someone tell, are these brownish tips the sign of the heat stress or something else? And how bad is that for the plant's not so distant future? She grows indoors. Peak DLI was almost 60 but very briefly about one night. Now it's dimmed to 40dli/~600ppfd/ 20/4 schedule.
