I've got 10 myself growing but I am going to mother one out. I have 10 AK-47 as well and I am noticing the Crimea is much more indica and slower moving. I would have to agree they do look a little early but if the tri's are amber then you should be good. Normally I think if you have new growth (white hairs), I would wait till those taper off, but we also assume they mature at the same rate as the tri's.
Did you ever get a chance to try this stuff out? Apparently this does't turn Blue as one might assume.
