I feel like it might be a calcium deficiency or something because this is reused soil that I used. And spotted dots I’m seeing on forums are similar to a calcium deficiency. I bought some Dolomite lime. I’m wondering if anyone has any advice before me topdressibg it 2tbsp/gal.

Looks similar to black spot fungus on roses. I use neem oil at night.

Doesn't look like calcium deficiency.. Do you have a loupe to take a closer look?

I don’t really see many pests on it other than maybe a couple of weird coloured flies here and there. The underside is clean no eggs from the naked eye. Any ideas on how to deal with it before I lose this big bush ?

I was able to get this from the garden Center near me. Should I use this?

It's sooty black mold. It grows on honey dew from aphids. It is not harmful to the plant.
Get yallow sticky traps and use an organic pesticide like spinosad or bt and an alcohol/ water spray from an airless paint sprayer..
