What is this leaf showing?
Anybody knows what is going on with this plant? My first guess was nitrogen toxicity because of the leaves clawing down a week ago, but I am not fully sure anymore with how the leaves are looking now.

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?

Why my plant is in shock i fixed the ph of watering .I suspect of this reasons:Heat wave/changing phase to flowering / nutrient locked/ over watering/. In
I lowered the ph of watering from 6.8 to 6.0 but this plant is still is shock and wont grow like others. Could it be a sign of changing phase from veg to bloom ? 3 weeks ago my first plant went to flowering and did the same color fading. Now that plant has good color

Yellowing on lower leaves. Any idea what this is?
Don't think they should be deficient in anything yet, they're in new Ocean Forest soil and only on day 11 of veg, no way they used up what's in the soil yet. More details in my grow diary comment.

Yellowing leaves help please (newbie)
Hi guys, had a calcium/ magnesium deficiency last week which I have treated with calmag this week However I’m concerned the plant is yellowing more. Is this still related to the same issue ? I understand the brown spots won’t be reversed but should the leaves still be yellowing?

Grey leaf tips
Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?
