    Frequently asked questions about Royalmix
    Yes, but it only makes sense adding Supermix if you have already harvested a crop from this soil. These soils have maximum fertilisers if they are unused.
    Our Royalmix is maximally fertilised. For young plants that are not yet accustomed to high EC-values, it may be difficult when they are suddenly planted into a maximum fertilised soil. Therefore we recommend to flush the Batmix before putting the plant into the Royalmix. This is done by filling the pot (eg 10 liters) with Royalmix and  rinsing it with 5 to 10 liters of water. After this, the plant can be planted directly. The fertilisers that are absorbed directly will be flushed out with the water. Within the following days, the EC value in Royalmix will rise again and gradually the non absorbable fertilisers will be released.
    No, combined with our 100% NATURAL Grow Style you don't have to regulate the pH value.
    Normally you'll notice the leaves starting to turn yellow after 6 weeks. This is a sign you need to start fertilisation.
