Light burn, light burn due to humidifier water lights?What do you think caused this brown color on that leaf? I have 5 leaves like that, all the others are ok.
I believe it's due to pulverizing water and droplets acting as magnifiers for the light, causing small burns.
Also, since they are burnt, should I just cut them out?Week 7

I have no idea what these brown spots are on my seedling?Brown/ rusty looking spots on seedling. Only thing I did was spray with a Epson salt and B52 foliar spray. The soil is deprived of magnesium so that’s why. I think I corrected by using cal mag. The sister plant is a few weeks ahead and showing recovery.Leaves. Color - Dark-brown

Brown spots on lowest leavesHallo Freunde!
Ich habe an den untersten Blättern meiner Pflanzen, Verfärbungen auf der Blattoberseite entdeckt. 😲
Ich vermute das etwas Überdüngung die Ursache ist. Week 3 Day 19
Wenn jemand die genaue Ursache und wie ich es behebe, erklären könnte?
Vielen Dank 😗

I am seeing an issue with the lower fan leaves and it seems to be progressing upwards. The leaves are yellowing and also seem to be turning brownish. I added CalMag into my last feeding but beyond that not sure what I should consider, info/advice is appreciated. See last pic wk5.Week 5

Why leaves brown? (urgent)Some leaves turn brown as in the photo. Leaves in the middle turn brown first, then bottom leaves. Now I try making larger lamp-to-plant distance and feeding less nutrients, but no good sign appears. Other conditions are stated in my diary. Why do you think it is?Week 7
