    That would be blossom end rot! This is caused by lacking in Calcium (and Magnesium, since they are taken up together, but many people don't know this!) There is a very simple way to fix this problem. All you need is DOLOMITIC LIME. That's it. It supplies, both, Magnesium and Calcium at the same time. There are many ways to combat this, but this is the easiest (and least expensive) way to go about this.

    Can blossom end rot also appear from the side of the fruit? In all the example pictures I've seen online the blossom end rot develops in a uniform way around the withered blossom - on my fruit it's appearing on the sides. I just wanted to be 100 percent sure it isn't another condition. I will still treat it for blossom end rot in the meantime - I can't see it doing damage if it's not the case! I think you're probably though right by the way - judging by the artcile that you linked to me (we've experienced extreme heat followed by heavy rainfall plus I have many plants in a large tub meaning they've all received some nitrogen at varying times in their development etc).

    This is typical of tomato wilt disease. Go ahead and harvest any tomatoes, then dispose of the plant in the trash. The soil should be thrown out. Make sure to wash the container thoroughly before planting again. Use a 10 percent bleach solution when cleaning the pot.

    Without a photo, probably not with accuracy. I could take a few guesses and get you started in a direction, though.

    If it has been wet lately, then it could be the start of a fungal infection. In this case, you will need a fungicide: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm

    You can also use DOLOMITIC LIME and WETTABLE SULFUR to help with your issue.

    It could be insect infestation, as well. I couldn't say which, without seeing the damage, but it could be a number of pests. This article will give you more information on insecticides: https://www.gardeningknowhow.com/special/organic/what-are-organic-pesticides.htm

    Unfortunately, there are many causes for this depending on exactly, how it looks, and where it occurs. This article will help you to narrow down the possibilities: https://www.gardeningknowhow.com/edible/vegetables/tomato/yellow-tomato-leaves.htm

    It is just a little blurry, but I do see the culprit. Pseudomonas syringae, or Bacterial Speck.

    There is no real treatment once established, but you can prevent it next time.

    This is blossom end rot. This is caused by a lack of calcium, and often magnesium. The solution to correct this is absolutely simple, but can be caused by environmental factors as well.
    Dolomitic lime works well. It will provide calcium, magnesium, as well as keep the soil pH balanced. This, alone, will stop the rot completely most of the time.
