It's probably just nothing man and will continue to grow well. Sometimes they have like birthmarks while they emerge from the seed

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.

Fungus or deficiency?
I have these gals growing outdoors and have a few leaves that look like this. Appeared after multiple heavy rain days. Applied nutrients yesterday so I still need to wait for the results. Is this a sign of fungus or deficiency?

Brown patches on leaves
Noticed these marks on the leaves of the plant I've had problems with. Any ideas what they could be? The other two are smelly amazing and the single plant is so sticky! I think it might be the cheesecake but I'm really not sure, I won't make the mistake of mixing them up again

leaves dry and curling up
Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches
