hi, well the Question if they locked out or a defiency, should not Play a role here. The Plant is close to Harvest, and thats what she Looks like, leaves are discloring, pistils are ripe. And you may check the trichomes.
As aim having no datas of your preevious weeks i cant say what happened here. But Maybe you cut your Vegetation fertiliser too soon. You may give them those, until they are Ready with the strech.
But as I mebntioned, her Optik is secondary. Girl seem to be Ready for Harvest... happy growing
