I'd highly advise you learn to grow using synthetic nutrients that are readily available in final form. All organic really means is "yet to be broken down". In a perfect world organic is better as its all about the micros, but you lose your ability to control your nutrient ratio which can easily be skewed.
The more organic processes you have being broken down the more chances you have for losing control.
Copied the following from Google to give you a idea.
Complications of exceeding 5% organic matter
1. Nutrient imbalance and toxicity
Mineralization surges: During decomposition, organic matter can release large amounts of nutrients in a short time. This sudden surge can lead to nutrient toxicities and inhibit the plant's ability to absorb other essential minerals.
Excessive nitrogen: If a large volume of low carbon-to-nitrogen (C:N) organic material (like some manures) is added, it can release too much nitrogen, leading to excessive vegetative growth at the expense of flowering and fruiting.
Salt buildup: Composted materials, especially manure-based compost, can contain high levels of soluble salts. Without regular leaching from rainfall (as in container gardening or high tunnels), these salts can accumulate and cause plant toxicity.
Excess phosphorus: Manure-based composts can also lead to an excessive buildup of phosphorus. This can interfere with the plant's uptake of other nutrients, such as iron and zinc, leading to deficiencies.
2. Poor soil structure and aeration
Compaction: Incorporating a large amount of organic material into wet soil can lead to compaction as it decomposes, displacing air pockets that plant roots need to breathe.
Waterlogging: A heavy composition of organic matter can cause a growing medium to hold too much water. This leads to poor drainage, suffocating plant roots and fostering anaerobic (oxygen-free) conditions that can kill beneficial microbes and promote root diseases.
Breakdown of structure: As organic material continues to break down, the medium's structure can collapse, reducing overall porosity and aeration.
3. Allelopathy and pathogens
Allelopathic compounds: Some plant-based materials, like wood chips, can release chemical compounds during decomposition that inhibit the growth of other plants. This effect, called allelopathy, can reduce yields and suppress root growth.
Disease: Excessive and unmanaged organic matter can harbor pathogens and increase the risk of disease, especially in greenhouse or high-tunnel settings.
4. Nitrogen immobilization
High C:N ratio: Conversely, if the organic material has a very high C:N ratio (like sawdust or straw), microbes will pull existing nitrogen from the soil to facilitate decomposition. This can temporarily rob plants of nitrogen, causing a nutrient deficiency.
How to use organic matter correctly
The correct approach is to add organic matter gradually over time and monitor the soil's composition. For gardens, applying a half-inch layer of compost once or twice a year is often sufficient. For raised beds, a mix of mineral soil and compost (starting at around 10% compost by volume) is a better starting point than using pure compost. A soil test can help determine the existing organic matter content and guide a more precise application strategy.
Good luck in your growing journey.
