I just got this Trident Maple Forst for my B-day about 2 weeks ago from my son’s the first that I received cane with the base all broken in pieces so they sent me a new and I had to re-pot the first, I used a Akadama mix soil it was doing well nothing apparent but I live in Yucaipa and for the last week it’s been non-stop light rain or drizzle so I have not watered them but three days ago I noticed these black spot all over the leafs and I don’t know what it is or even what to do to help my little trees? I keep them where they can get the morning sun for about 4 to 5 hours then it’s shaded. If someone could give me some guidance I would so appreciate it. Thank You !

Gina Marie, welcome!
There is a link that can help you, I will post it below:

But, to narrow down your search, it could be:

Phyllosticta

Like anthracnose, phyllosticta leaf spot (phyllosticta minima) is caused by a fungus.

Description: phyllosticta causes raised tan or dark brown leaf spots. The spots may turn dry and brittle and crumble away, leaving holes in the maple leaves.
How it spreads: As with anthracnose, the fungus that causes phyllosticta spends its winters hiding among the fallen leaves on the ground. It waits until the springtime, when damp conditions give it the opportunity to spread. Breezes carry the spores to new hosts.
Prevention: Rake up fallen leaves each autumn and discard them properly to prevent fungal diseases such as phyllosticta.
