I've had this before, mine was due to calcium/magnesium deficiency, are you using calmag as part of your feed?

Schützt sie sich?
Diese herabhängenden Blätter... was verursacht dieses Symptom? Hab noch kein Tagebuch über die (online) aber die Pflanze hat einen Schaden an der Pfahlwurzel seit sie ein Keimling ist. Ich hatte aber auch die RH nicht im Griff. Die war jetzt die letzen 2 Tage bei 45%. Zuvor ok.

Big difference in first true leaves' size
Big difference in first true leaves' size Its almost day 5 after emergence. Is this normal? Should I be concerned? ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

Orange dots
Too much stress and light maybe? Should I use a little bit more of CalMag for this lady? This is a Mexican Airlines on day 12, topped. I know these are really small dots, but I like to prevent.

Spots on leaves after spraying with Plagron Vita Race
On the 4th of March during lights ON I sprayed my plants with distilled water with Vita Race (3ml/L). I noticed that after it dried up there are some weird spots on the leaves that were left behind (see picture). Any idea if that can lead to problems later?😅
