Hey y'all!

I recently started a container garden on my apartment patio. I have a few ornamental plants, but my problems are arising with the fruit and herbs. Although I have read a bit about companion planting, I am still not sure if one thing is affecting another, so I will explain my setup:

On one side of the patio are a jasmine and bougainvillea. Next to them, all in separate containers, I have: A dwarf lemon tree, a mexican lime tree, tarragon, thyme, red onions, tomato, 3 kinds of mint, lemon balm, jalapeño pepper, basil and oregano.

On the other side of the patio I have 2 ficus trees, sage, parsley, rosemary and lavender.

I also have succulents spread about but doubt they affect anything.

Below are my issues (I have numbered each actual question for easy reference):

1.Is there a patio safe spray I should use for lime trees?
2. Below are my lime problems. Do I have a combination of problems and can I treat with just one spray?
- I think my lime tree possibly has an aphid/fungal combo problem.
- Some leaves are curling and browning.
- Some leaves have light trail looking marks on underside.
- Some leaves have black dots and webbing on the underside.
- Some of the buds have turned black although there are still about a dozen growing limes. The half of the tree with less leaf curl seems to be producing more limes.
- My local nursery recommended Liqui-cop for my lime tree but the more reading I do, it doesn't seem appropriate for use on a small patio.

I think my chocolate mint has aphids.
3. If my mint and lime both have aphids, can I use the same patio safe treatment on both plants?
- Some mint leaves have small black dots and white webbing.

Some of my basil leaves seem to have a crinkle effect while others are more flat.
4. Is this basil leaf crinkle effect normal or just a watering issue?
5. Do I need to treat with a spray?

My lemon tree has tons of healthy looking lemons but the leaves have lost some of their luster and green intensity.

- I have a 4-4-4 basic fertilizer and a 4-8-2 that I use on my ornamental plants.
6. Is this dull leaf effect a lack of fertilizer?
7. Is this 4-8-2 safe/beneficial for my lemon and lime trees?
8. What is the best fertilizer for container lemon and lime trees?
