Ist es das einzige Blatt, stellt dies kein Problem dar, da die Pflanze insgesamt gesund aussieht. Um die Pflanze zu kräftigen und die Verzweigung anzuregen, können Sie sie jedoch entlauben und lollipoppen.

It’s looking like the start of a calcium deficiency. If you have not been providing the plant any additional calcium thus far, it’s likely your issue. Your best bet would be to give it a dose of Calcium in your next feed/water and see if the issue stops developing on more leaves. Hope this helps.

Brownish Spots on 2 Older Leafs. Young plant.I searched it up before posting this and what I found is: Leaf spot, canker, and fungus: Brown leaf spot, Yellow leaf spot, Cladosporium stem canker and Chaetomium fungus. Solutions I found in the comments below. What do you guys think? Can it be heat (a lot of hot days here)?

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.

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.
