Cool... yeah i've been checking the difference every day between the lower bud sites and the main colas and since my last post the lower parts of the main colas have started to turn amber, but the tops are still leafy and un-crystalised, so I guess that is yet to come.
Good news is they have pretty much stopped growing vertically (thank god!) and have started to fatten up.
My plant is suffering with severe nitrogen deficiency so I hope it makes it another 6 wks (no fan leaves except at the top and they are lime green

) I'm using crap Ionics nutes which don't seem to be working, although i've read that it's normal for the plant to become deficient during flowering. Still there is plenty of smaller healthy leaves so it should make it through.
