Harvest in a week or she needs more days?

Looks longer than a week. if you start scoping trichomes too early, you will find mature trichomes, but if the plant isn't near the end, this is misinformation. The calyxes around the white hairs need to plump, first. then start looking at the trichomes - only on calyxes, not on the leaves. if you start getting too much fade, do start up the fertilization again. you may have 2 weeks remaining. It's hard to guesstimate accurately.

Not yet, she is still bulking up a bit. She's not foxtailing and still has a lot of white pistils, so you have at least 2 weeks left, probably 3. Personally, I would keep giving a light feed for another week and then stop and just give water. She's looking great and will have some nice spears from her.
