Looks like Heat and overwatering + calcium deficiency possibly caused by Potassium excess.

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Magnesium nutrient lock out, triggered by too much potassium ?
@Burmese Thank you so much for your help. 🙏😊 I think it was a magnesium nutrient lock out, triggered by too much potassium. I sprayed some water with Epsom salt on the leaves and it looks like it is getting better. 👍😉

Hello guys! Overall the plant looks light green/yellowish and pretty small, with short internodes and bottom leaves with burnt and curled up tips. I give water every 3/4 days and commonly suggested fertilzers quantities. How can I let her recover and get bigger? Thanks :)

Starting to fade? Or nutrient deficiency?
One of my plants has several fan leaves that are turning yellow/purple, and I can't tell if it's low on N or starting to fade. The plants are 2 days into week 5 of flower with a 9-10 week flower period, so it seems a little early for it to be turning colors like this.

Unser erster Grow! Wir haben Nährstoffbrand, wie schlimm? Was können wir noch tun? - Dünger: Canna Terra Vega - Erde: COMPO SANA Qualitäts Eerde - 50%
Vor genau einer Woche haben wir einen Nährstoffbrand festgestellt. Die Symptome waren zunächst eher schwach, mit einzelnen, gelb hängenden Spitzen. Nun sieht es so aus wie auf den Bildern. Haben bereits im nächsten Guss ohne Dünger mit ph 6,3 Wasser gegossen. Was noch tun?

Identifying the cause of stress
Does anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?

If they have been over fed how do I fix it? Over watered just needs to dry out and not do it again. Sigh that's the part I keep having trouble with

Yellow leaves
The lower leaves turn yellow Is it due to a lack of nitrogen, or is it self-defoliation of the plant? (photos at week 5) I look forward to your advice) Should other leaves be defoliated or left as they are?
