NFT 2xNorthernLights 1xOrion F1

Hello my friend, you can clearly see that the growers below do not know what a NFT system is XD I use ebb and flow myself. But I would refresh my nutrient solution for a last time and lower the EC to 1.5 to prevent further nutrient burning and a faster nutrient uptake. When you do not want to change your nutrients (and I would also not do this in the last weeks) then there is not much else that you can do. And my biggest issue is always the sneaky pH rising in my system. That is why I use Canna Aqua now. Problem solved but this is always a problem to keep an eye on! Goodluck mate!
