Hello my friend, you need to do a flush to flush out the nutrients from the soil. You want to use the pot volume in water. So if you got a liter pot then you use 10 liters of water without nutrients with pH 6.2
When you have done this you let the water drain away. Then let it dry till the top inch is completely dry before watering again with nutrients. 75% from the previous given nutrients will be enough!
Enjoy this grow buddy!
