You must be careful with the tomato food version. Some plants other than tomatoes can not handle the high phosphorus load and will be stunted.
Tomato fertilizer can be used on other flowering and fruiting plants, but it's essential to be cautious with the nutrient levels. Consider using a well-balanced, all-purpose fertilizer for a wider range of plants to avoid nutrient imbalances. Follow instructions and avoid over-fertilization to maintain plant health.
Type of Plants: Miracle-Gro is generally safe for many garden plants, including vegetables, flowers, and shrubs. However, certain plants, like succulents and cacti, may not require such high levels of nutrients and can suffer from over-fertilization.
For use on: Use on all varieties of Tomatoes. Can also be used on fruiting crops like peppers, squash & melons.

Water sparingly as they don't like to be sitting in sodden compost. If you haven't added any fertiliser when planting give them a weak feed of Tomorite or other tomato food once a week, this promotes the formation of flowers.
A fertilizer for growing tomatoes is suitable for all fruiting crops, including zucchini. It will contain NPK and in particular be high in phosphorus and potassium. This will help zucchini plants to develop and ripen fruits. Tomato fertilizer will also contain calcium to help prevent blossom end rot.
Tips for Feeding Tomatoes and Peppers:
Feed single plants with 3 tablespoons of Tomato-tone. For rows of plants, apply 1 cup on each side per 5 feet. Feed potted plants 1.5 teaspoons per 4” pot diameter.
Flowering plants should be given houseplant fertiliser every two weeks in spring. Increase this to a weekly feed, with a fertiliser rich in potassium, in the run up to flowering. Tomato fertilisers are ideal for this – but dilute by half the recommended dose as they can be too overpowering for indoor plants.
MG is so strong that if used incorrectly, the fertilizer will actually burn the leaves and roots of your plants (you may have already experienced this). Imagine what it's doing to the healthy bacteria, fungi and other soil microbes that are working so hard to provide the nutrients your plants need.
As opposed to Miracle-Gro which offers synthetic NPK (Nitrogen - N, Phosphorus - P & Potassium - K) and little else, Neptune's Harvest products, made from fresh North Atlantic fish, contain vitamins, micro and macro nutrients, amino acids, and natural growth hormones.
Depending on the contents of the fertiliser, over-fertilised tomatoes can display burnt roots, excessive leaf and shoot growth, growth disorders, and stunted growth, all of which increase your plant's susceptibility to disease. If that wasn't bad enough, tomato fruits also suffer from over-fertilisation!
Tomatoes require more potassium than other types of plants, so a 3-4-6 fertilizer is your best bet for preventing tomato-specific issues like rotting. Grass requires more nitrogen, so you'll want a fertilizer with a higher ratio of nitrogen like 24-4-12 or 20-2-6 for your lawn.
Houseplants should only be fed when they are actively growing and not when they are resting. In general, the majority of houseplants should be fed every second watering during the growing season (spring and summer), which is probably every 10 to 14 days.
The good news is that these two categories of veggies can benefit from the exact same type of fertilizer. Many homeowners prefer using organic fertilizers for tomatoes and peppers.
Tomatoes are prone to magnesium deficiency later in the growing season, which can show with yellowing leaves and diminished production. Ultra Epsom Salt treatments at the beginning of their planting and throughout their seasonal life can help to prevent and remedy magnesium deficiency in your tomato plants.
So here are a few things that will help your vegetables stay beautiful and taste great: Cayenne Pepper: Cayenne pepper won't hurt your plants but it will keep many small animals away. Every few days, sprinkle about ¼ cup of cayenne pepper throughout your garden.
Potassium. To get good yields of tomatoes, runner beans, squash, chillies, strawberries and other fruiting crops from containers, you need to regularly add additional potassium (K). The easiest way to do this is to buy a bottle of tomato feed. Although called tomato feed, this will do the job for all fruiting crops.
When your cucumbers start to flower, feed weekly with a high potash fertiliser, such as a liquid tomato food. Cucumbers bear male and female flowers and in the greenhouse, you will need to remove the male ones, as pollination can make the fruits taste bitter and be full of seed.
A good all-purpose fertilizer would be a 10-10-10 NPK (nitrogen, phosphorus, and potassium). This type of fertilizer will work well for most plants and soil types.
With feeding during the summer spring and summer months feeding with liquid tomato feed which contains lots of potash will ensure lots of flowers. To create a deeper blue coloured flower feeding with some iron such as iron sulphate will help create a deeper blue coloured flowers.
Coffee grounds are often recommended as a cheap and environmentally friendly fertiliser for geraniums or houseplants.
