Trying to figure out what went wrong with my tomato plants. I have a couple issues. This is my second year with a garden so I'm still new and learning. Last year our plants produced very well until the horn worms destroyed everything. This year our squash and zucchini are doing well and look very healthy. Not sure if its the soil, bad plants, etc.

The first two pictures are both early girls but one is growing very good and the other not so much. The one that isn't growing well is still producing fruit but that's about it. Not sure why one has dark green leaves and the other light green. They were both bought from the same place and planted at the same time about middle of March.

The next issue is with my better boy plants. They were bought as a 4 pack and all planted at the same time as my early girls. Not sure what is going on with them but they look terrible. They have dark green leaves Each one is producing fruit but has not grown in height in a while. Any help would be greatly appreciated.

One last thing is some leaf issues? The first picture of the brown spots is from a cherry tomato plant that is producing fruit but not sure what the spots are from. The other two pictures show white spots that have started to show up on the leaves of two of my other plants. Any clue as to what these are?
