Hello
@Stooooned. Nah, it isn't. But if you want to take some preventive measures you can add trichoderma harzianum (its an aggressive fungus) like bioponic mix from GHE. Then stop it and add a mycorrhiza . After the mycorrhiza has establish and you have a simple DWC system ( not under current that uses water pumps ) you can give in the bucket a compost tea. It will make your roots very white. Happy growing ! 👊
