It is perfectly normal for tomatoes to shed their lower leaves, it's part of the plant's life cycle. Happens all the time.

With the liquid nutrients, are you doing a foliar feed or just fertilizing into the soil?

Fertilizing every day would burn any plant in a potter, most container gardeners take the recommended fertilizer rate on the box/instructions, cut that in half, and feed/fertilize at that half rate only once a week.

In containers, it's best to put the container in a large enough bin and allow the soil to soak up water put in the bin from the bottom up. I had an upside down tomato plant a couple of years back (my first attempt at growing anything) and I learned why those topsy turvy things dont work. The plant sends out feeder roots as far down as they can, or in the case of the upside down planter, UP.

I would water from the top of the upside down planter, but gravity just took the water down to the bottom, and the moisture never soaked in.

In thinking about a regular container, the next spring I was watering my seedlings in their tray from the top of the tray, soaking each cell. They would look sickly from time to time, and I thought I was doing something wrong. When I went to transplant them, I watered them again, from the top, splashing water into each cell.. and when I went to transplant them, the top of the potting mix in the plastic cells was sopping wet, and the bottom half of the potting mix was bone dry.

pulling the plants out of the cells when the bottom was dry destroyed the roots, and I lost two 72 cell trays full of peppers last spring, it was awful. Since then I have always watered from the bottom, the soil/mix will get dripping wet on top after a few minutes.. it's kinda cool.

If you water from underneath, you can be sure that the entire soil profile has taken all the water it can, then you only need to water them every 2 or 3 days, depending on the size of your containers. soil mixes can hold a LOT of water in them, if you let them work like a sponge.

How large the containers should be -- if you want to keep them in containers as opposed to in the ground -- depends on what varieties you are growing.

Most determinate varieties (sometimes called "bush") would need at least a 5 gallon container, and indeterminate varieties (sometimes called "vining") at least twice that size. However, there are also dwarfs, basket types, and other small tomatoes which would do well in a smaller container.

[To determine the size, calculate the volume of the container in cubic inches, then divide by 231 (the number of cubic inches in a gallon). Or post the info and I'll calculate it for you. [Remember to measure the inside of the container; if the top and bottom are different lengths/widths/diameters, you'll need both measurements.]

When containers are much too small, plants will be unhappy and there will be less fruit and smaller fruit. In really hot weather, it's difficult to keep plants well-watered in too-small containers unless you have a drip system or can water multiple times during the day.

The burned circles in the leaves might be sunburn, which can occur if the leaves are wet (watered from the top; rained on; etc.) and the mid-day sun shines on the leaves. Think of how a magnifying glass can start a fire: same principle -- the drop of water on the leaf acts like a magnifying glass in the sun. For this (and other) reasons, it's best not to spray water on your plant; any sprays or foliar feeds you use should be applied in the evening or when the plant is in shade.

But are you certain you want to "kill or repel" all insects on contact? What about the bees that shake the flowers and aid in pollination? What about beneficial insects like ladybugs and their larvae, lacewings, etc.?

foliar: of, relating to, or applied to leaves.

Think "foliage."

oh, can't wait for pics, we gardeners love showing off and seeing others' work.

Drill several 1/2" holes in the bottom of pots for good drainage, place pots on heavy duty plant dollys and drill holes in dollys for drainage, so you can move them easily if need be plus if they are on a deck wont rot the deck.
put about 2-3" of mulch on top.

Water them nicely everyday, fertilize them about every 2 weeks.
When you transplant them, cut off a few of the bottom leaves especially ones that are yellow and plant them deep.

After a week or so they should be in good shape unless you have some kind of virus.

Like this.

Hard to say what that is, sorta looks like some sort of Verticillium Wilt, but the rest of the plant looks decent so might not be anything to worry about yet unless you see it towards the top of the plant and not just the bottom leaves.

One thing you need to do though is transplant to a larger pot. Maybe it just looks smaller in the pics but it looks no larger than 3-4 gallons.

They don't look like diseases, it just looks like a buildup of tap water compounds. You could filter the water if you wanted and see if that makes a difference, but that's a lot of work for so many plants.

Also, it would normally try to grow large-to-very-large tomatoes (some say size averages 10 oz., others 1-2 lbs.). What will happen if it remains in that small pot is more than I can answer.

Whoever grew that tomato and put it in that plastic container should be tried for cruelty to plants.

That is all I have planted this year, is 2 Bush and tomorrow planting 3 Dwarf's.
Still need to be in large containers minimum of 10gal, preferably 15gal but much easier to handle.

I have a couple Better Boys in ground and it can get 6-8 feet tall easy. I don't know if you'll be able to successfully transplant to bigger pot now, without loosing all those tomatoes.

You will have to water them daily in that pot, and tomatoes you'll get will likely be below par. But still better than store bought of course :D

I also wanted to include a picture of how the green beans are turning out. They have finally started blooming.

And of course, the radishes I just transplanted:
