It's my first time doing hydroponics, I am using the GH Flora series. Yesterday I changed my Basil's water to use those nutrients, along with epsom salt and CaMg.
Everything was fine all day yesterday, and today, until a few hours ago I checked and everything was "bad".
Here is a folder of all the pictures:
The plant still looks healthy for now, and obviously I shouldn't have a clear container, but I noticed this same stuff in one of my other plant's containers, which was spray painted opaque.
Any insight would be helpful, I don't want to mess up really bad :(
