How to Use NovaTec Solub 21 Fertilizer:
Open the Compo Expert NovaTec Solub 21 pack carefully and measure the required quantity using a clean spoon or weighing cup.

Half-fill the spray tank with clean water.

Add the remaining water and mix thoroughly to form a uniform spray solution.
Use a fine-mist or hollow-cone nozzle for proper coverage.
Spray during calm weather, covering both upper and lower leaf surfaces.
For drip irrigation, dissolve the required dose in a small volume of water first, then feed into the drip system.
