Italian Cypress HELP!

[Nicks_Bonsai]

Can anyone help with my Italian Cypress can't seem to find much help, I know it's not a common bonsai to have but I'm guessing it's similar to a juniper.

Basically was repotted about 2 months ago and have only recently within the last week or so noticed that some of the foliage is turning yellow and falling off when touched

I'm currently spraying the foliage with HB101 not sure if this will do anything.

The majority of the foliage seems fine, it's in full sun most the day and watered once or twice a day if needed.

Any help will be greatly appreciated

Yellowing foliage is typically a sign of root issues--too much or not enough water. A better pic of the soil might help. Looks like Akadama?

They really dont like too much water, very fast draining soil and all the sun and heat you can give it, if the new growth looks fine dont worry too much
