No deficiencies, everything is looking good. All the pics I just put up are drinking jacks and liking it. I think stuff is stickier on Jacks. I'll know better as I start indoors with it. Adding the rocks to the concentrate jug seems to be helping.
A better solution for me is to just make a smaller mix from the onset, like a gallon instead of two. That way I'll go thru it faster and fresher.
