Hello, I am new to the gardening world, trying to get over my previous black thumb on probably too large of a scale initially. I have a couple of tomato plants growing on my porch, and while they have been good so far, they are beginning to have problems. Rather then post one thread for each plant, i thought I would lump them together to save space on intro. They are all potted in miracle grow moisture control soiless potting mix. They have been getting good sun, but it has been pretty wet in illinois.

First one is a husky cherry, and in terms of fruit it is great. Already picked a couple of delicious ripe cherries off of this, and it has dozens more on the vine currently. Lately I have been getting some spotting which I couldn't identify online though, and some yellowing on the bottom leaves:

This spotting is all over the plant. It looks white up close, basically like all the green has faded from the plant. I have had no problem with pests on this plant, though there are a bunch of what I assume are Fungus Gnats in the soil and bottom stem.

The next is a big beefsteak plant. It is giant, and hasn't set fruit yet as the blossoms keep falling off.

For the most part the plant seems healthy, and is growing like a weed, but the bottom again is yellowing, and I am getting more spotting in places.

The third is a smaller roma variety, and again no fruit has set. For the most part it looks pretty healthy, though it did have a mite outbreak a couple of weeks ago that took a bit to get rid of.

I am concerned with the whitish spots again, as well as the darker rot looking issues on some leaves.

The last is a better bush plant, and it is pretty sad. Not really sure what is going on with it, but it has been hit the worst:

I know this is a bunch to throw in a thread, and I really appreciate any help that anyone can give me on these questions. Please let me know if I should include any more information, I am pretty new at this so I don't really know what more to do.

Thanks
