Black/redish spots on leaves
Gabriel_ODstarted grow question 2 years ago
Guys, I am seeing these kinds of spots on few of my plants. My immature guess is some disease (possible fungi) As a treatment I already cut those defected leaves and throw away before it infect whole. Anyone what are those? And how should I cure or prevent them?

Thank you for all the answers, the reason I think this is a fungi infection is because there is a high humidity (up to 80%) during night lately and my dumb-dumb brain forgot micronutrient deficiencies also exists to check. I ordered soil meter via online and check the pH of soil as soon as it arrived.

Looks like a simple calcium deficiency to me, not a disease of any sort.

The one piece of critical information is missing from your diary - your pH... I think this is the start of a calcium deficiency but WHY you're getting this is going to inform you on how to treat it - and throwing calmag at it is usually not the answer. If your pH is not in a good spot (6.0-6.5), no matter how much calcium you give her, the plant will not be able to absorb it... so first of all, check the pH!
She's also looking quite pale so I would increase the NPK nutes you're providing her... being careful not to overload with nitrogen as an excess of THAT nute will cause a lockout as well....
Good luck!

salut, soit un problème de ph ou alors peut-être une eau calcaire si tu arrose à l'eau du robinet. Ou les deux.

This is either potassium related or cal mag related. You should not of cut leaves away till problem fixed. Now it will suck nutrition from healthy leaves. Causing more leaf loss. I would increase those 3 nutes. Good luck and happy Growing. 🌱

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.

Is this septoria or alternaria?
The plant is doing well, buds are not affected (at least not now) so I hope it’s septoria. Few weeks till flowering complete, do you think I can carry on with it?
Please tell me it’s septoria and not alternaria. Thanks to anyone that will respond

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?

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.
