Sieht für mich eher nach beginnendem Magnesiummangel aus als nach Windbrand. Die hellen Zwischenräume bei noch grünen Blattadern sind da ziemlich typisch. Kann sein, dass durch die letzten Tage der pH im Substrat etwas aus dem optimalen Bereich gekommen ist und dadurch Mg schlechter aufgenommen wird – auch wenn eigentlich genug drin ist. Ich würde als Erstes mal den Drain pH checken (bei Erde so um 6,2–6,5 anpeilen, bei Coco 5,8–6,0). Wenn der passt, kannst du leicht mit Cal-Mag oder etwas Bittersalz nachhelfen. Achte drauf, nicht zu übertreiben, sonst schießt dir das Verhältnis zu anderen Nährstoffen durcheinander. Die alten Blätter werden sich nicht mehr erholen, aber neue sollten dann wieder normal aussehen. Guten grow noch 😊

Yes, magnesium deficiency. When growing in coco coir, you need to add supplemental magnesium from virtuually day one. It is not "wind burn". Remember too, what is showing in the leaves now, is a direct reflection of what was happening in the root zone 2 weeks ago..............in other words, this problem has been manifesting itself for some time already.

Nute burn in late flower I've encountered some late stage nute burn and have brown and twisted tips on fan leaves as well as some bronzing. I am reading different treatment options for nute burn online but what else should I try at this late stage? I flushed ph'd water w/calmag and it's slowing a bit.

Started LST but now plants look a bit sick?I attempted to do LST but I think I've maybe started too early as some of the leafs started to wilt kinda bad afterwards. Was careful not to break anything. Edges are curling and have discolored. I have a feeling they're a bit short too? Photo from 5 days ago and today.

Does the curl here (pic- Day 10) look like mild heat stress? Temps hover around 23-24°C (~75°F). RH ~ 65-75%. Water pH'ed to 6.5. Soil runoff tests @ 6.4-6.5. She's due for a drink tomorrow...any experts feel like throwing me a tip? Am I just overreacting?

brown spots on older leaves The brown spots are appearing more prominently on the older leaves. Overall, the color of the leaves is rather light green compared to other grow diaries. What could I do to fix the deficiency?

Issue?Can’t quite work out if I’ve got a problem on some of the lower leaves on the cheese plant. You can see them starting to go a lighter shade of green. Perhaps someone can comment? Could it be Mag or N deficiency?

Praying leaves The leaves are stretching up (praying leaves as I understand). It's just 1 day after topping and I would expect some stress, is this a good or bad sign? I fear I might have topped them a bit too early.
