Hi there, for mineral/bottled nutrients it is generally good to stick with a line, and cut down the dosage by half to start. Measuring pH and EC would be very important for bottled nutrients, and you can message me a brand and I can give more individual feedback/nutrient regimes for that brand.
For organic ammendments like manure it's a lot more by feel as opposed to specific regimes. Manure is going to be high in nitrogen I believe so is better used during vegitative growth, but beyond that there will be factors like is the manure composted/broken down or still "hot" (which could burn the plants). It is also not complete, so additional compost/earthworm castings/bone meal, etc may be needed. You may find it easiest to use an organic "water only" supersoil that is premixed, and then top dress or add beneficials when needed. This is a lot more beginner friendly. These soils have all the nutrients they need, so you don't have to do much in terms of extra feeding. They can be expensive to ship, so look at what is produced locally to you because there are generally some good super soil companies in most geographic locations 🌱👍
