you should be nearing completion, at 7 weeks of flower ... NO more nutrients, just water, from here on ... try to keep your humidity down, so molds can't form in the buds ... GET a 30x magnifier, very necessary for correct determination, and not that expensive ... Radio Shack has a pocket microscope for about $10, surely other sources sell something like that, too ... very popular with growers ... the little 'light-cycle' tricks don't do anything, mostly urban myth ... don't expect that to make any difference, just go with 12/12 next time (there is some speculation that a couple days of darkness, just before harvest, forces resin into the buds (jury is still out on that, I'll believe it, when I see a difference) ... nice plants, they look healthy, good job :thumbsup:
