I just flush it 4 days ago because I think it got calmag lockout since I always give them around 5ml of calmag every watering. I only water when 2inch top soil dry with 1.5L of ph balance water. Not a fungus or anything that grow because It cannot be rub or remove from outside.

Nitrogen toxicity ( your overfeed ) caused calcium absorption problems.
Slow down with N, you don't need it anyway.
Give next watering only CalMag with up to EC 0.4 from it . It will stop problems spread, but spots will stay. You will need 2-4 to notice slowing down of problems progression.
Sometimes it is caused by too intense light too.
All the Best !

5ml/l of calmeg is more then double most brands. they tend to max out at 2ml/l
Less is more.

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.

Possible P Deficiency?Hey everyone, hope all is well. I noticed these past few days some dark spots appearing on some of my higher leaves. From what I’ve read it looks like it could be a Phosphorus deficiency. Any ideas? It’s on two out of three plants of the same strain. All same feeding schedule.

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?

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 😗
