Given plants, all have weird brown spots?
One of my friends has moved off to uni dorms so she gave me her plants to look after, I’ve noticed they all have brown/pale spots?
Today I put them in my bathtub, rinsed down with the shower head. Sprayed the soil with an antifungal/pest spray, wiped the leaves with a diluted neem oil, soap and water mix. They got a good bottom water too.
I have many cacti so I’ve kept these isolated in my bathroom for now.
I can’t repot them or take them out to look at the roots for pests as I have zero cococoir or perlite right now. I’ll order some on Amazon for it to come tomorrow.
Google says it’s a fungal disease?
What more should I do?
