I am thinking the BK v2 are mag hogs. I haven't posted pics of mine yet because they are showing heavy mag deficiency. I have a completely unrelated seed that came up in one of the BK containers and it doesn't show symptoms at all. I don't have access to sulpomag so it's Epsom salts for mine, foliar feed and soil drench!
Is it very difficult to clone, is that biker?
They look good to me, why you say that, you want more praying leaves?
