An all purpose greenhouse fertilizer, i.e. 20-20-20, is a poor choice for tomatoes. Tomatoes need a grade with much lower nitrogen and much higher potassium, as well as several other essential elements.
NPK 20 20 20 is a highly concentrated, balanced plant fertiliser. It contains equal parts nitrogen, phosphorus, and potassium. It is ideal for growing plants in poor quality soils as it provides a high amount of each of the three essential plant macronutrients.
Tomatoes need less nitrogen and more phosphorus and potassium at this stage. Look for something like a 5-10-10 fertilizer to encourage more flowers and fruit. Consider Organic Options: If you're into natural gardening, organic fertilizers like compost, worm castings, or fish emulsion are great choices.
