The very dark leaves could be a result from using the TEA. Dark leaves is a common trait from using TEA.
It could be the tea but if you look at some of my past AF grows a lot of them have that almost blackish forest green color. I think one time even MD asked me if those were real leaves or not because of that dark color. But with that said most of the AF's I have grown are from MD or connected to him and I was thinking maybe its the MasterKush he used way back when. It is in everything MD has done.
Either way they like the teat....
