Thank you.

Hi. Particularly in question was what I believed at the time, foliage had what appeared to be fungal issues, which the picture focused more on so I had thought.

The texture of the foliage doesn’t look like Shimpaku to me.
Oh, really? What does it look like?. It came from a class. I’m waiting until I get some more elongation to cut back and hopefully form some of the pads.
 
Are you talking about the yellow foliage? Thats pretty normal for interior foliage to turn that color. Lack of adequate light can make it more visible. Old foliage doesn’t stay green forever (and evergreens aren’t really evergreen. They cycle through foliage that changes over time)

Someone told me the little specks were fungal. I bought mancozeb and miticide for the mites.

The specks might be mite damage (fungus doesn’t really make small spots) but the yellow piece in the center of the photo is old foliage

Thanks for clarifying. Also to speak to this, I found Bjorn’s video on Shimpaku and it helped me understand further so I wanted to share that here too.

 
Mites are easy to test for. Tap the branch above a sheet of white paper, then wait about 20 seconds and check for movement of specks. If you still don't see any, wipe your hand across the paper. Brown/red streaks are spider mites. Green are your predatory mites.

The scale growth is too lanky and sparse to look like shimpaku. It looks a lot like standard landscape chinensis growth.

Just to clarifying though Metalhead, a chinensis is considered shimpaku, no?

Juniperus chinensis 'Shimpaku' is a dwarf, irregular vase-shaped form of the Chinese juniper, Juniperus chinensis. Originally native to Japan, they were first collected in the 1850s in Japan

No Juniperus chinensis can be a number of varieties, not just shimpaku.

Agree with others, the growth is weird for shimpaku.

Are the yellowish spots on the tips or pointy tips coming out of branches?

All shimpaku are botanically J. chinensis, but not all J. chinensis are Shimpaku.
Shimpaku is a specific variety of J. chinensis originally found in Japan, which has been propagated through cuttings and layerings and grafting because its growth traits and culture are very favorable to bonsai practices. It is treated like a ‘cultivar’, but really it isn’t.
