Instructions and Dosage
For optimal horticultural performance, prepare your solution according to these recommendations:

- Indoor flowering plants: Dissolve 5 ml (1 tsp) of fertilizer in 4 litres of water. Apply at the base of the plants every 4 weeks.
Application:
- Water the soil directly until well-soaked to ensure the solution reaches the roots.
- Avoid applying the solution to the foliage during periods of direct, intense sunlight.
- For best results, fertilize when the soil is already slightly damp.
