I water/feed with jacks every day. full strength. in Promix. white widow
Thats what I was told to do so I did it. It was hard to water every day as this is my second grow and the first was in soil. So I was afraid i would over water them. Nope… I water with tons of runoff every day and they take it like a champ.
Now a more experienced grower may tell you different but I am just going off on what everyone here told me.
