Satsuma trees

My satsuma tree leaves are looking dark. Maybe even have a black/gray film on them. Any idea what this is? I'm considering taking some of the leaves to LA Nursery or Cleggs in BR to see if they have anyone there that knows whats going on. Keep forgetting to take pictures.
We bought the house 2 years ago and our first crop of satsumas were large and puffy with no real flavor. This past year's crop were normal sized and very sweet, but the skin on the fruits was very thin.
I've never had fruit trees before this house, so I'm not sure what I need to be putting into them to get a good harvest. The trees appear to be maybe 5-8 years old.
ETA: They look similar to this photo (from google), but I've never seen any insects present.

It is more of a fungus, which is why you aren't seeing any insects. Use a horticulture soap or neem oil and spray down the tree and it will just wash off!

Sooty mold. Not harmful - mold that grows on sugar secretions of insects, like aphids, present on the leaves. Control the insects, you will control the mold. LINK LINK (page 22)
Puffy fruit is not uncommon on younger citrus trees , 4 or 5 years - tree might be younger than you think. Read the citrus manual I linked for management guidelines for your tree.

they make oil sprays to help control that condition. The last on I used when I had a couple citrus trees before Katrina's floodwater killed them was a product called Volic Oil Spray.
It also took care of Citrus Rust Mites that attack the skin of ripening fruit and makes it look brown and leathery, but they have no effect on the quality of the fruit. It just makes the fruit harder to peel.

Upthread advice is good. A spray of UltraFine Oil (that's the name of the product) or other horticultural oil will take care of it.
RE: fruit quality, puffy fruit is usually an indicator of a young tree setting more fruit than it can support. If the tree sets an ultra heavy crop this year, you might consider thinning it a bit so that the remaining fruit is quality.
It's time to fertilize, as well.

Does anyone have experience or opinion on this product?
No direct experience with that one but should work fine and I wouldn’t hesitate to use them. The speciality fruit and nut fertilizers likely contain higher concentrations of minor elements important for fruit trees not often present in regular vegetable fertilizers like 8-8-8 or 13-13-13. Listened to a local garden show couple weeks ago hosted by a pair of highly experienced degreed horticulturists, and it was mentioned citrus benefit from supplemental magnesium. So in their opinion spreading a little epsom salt (magnesium sulfate) at the drip line can be beneficial.

Spikes are usually more expensive than loose fertilizer. The feeder roots of citrus are fairly close to the surface of the soil, and spread out past the width of the tree's branches. I just broadcast it on the surface of the soil and "scratch" it in a bit with a rake.
An old nurseryman told me to skip those spikes and do this instead: drive a piece of rebar into the ground about 4-5 inches, then pull it out. Pour some loose fertilizer into the hole left by the rebar. Cheaper than spikes and gets a bit of the fertilizer below the surface.

This is what I do. I have a satsuma that will be 4 yrs old this year, last year had about 10 blossoms then tiny fruit but they all fell off pretty quickly. Hoping this is the year the fruit stays.

You drive those holes all the way around the tree?

Yep, sooty mold. Hit with with the NEEM oil.
