Sorry I must not have been clear. The leaves will dry up if the plant is dead. The leaves on my plant last year dried up because I killed the roots, and therefore killed the entire plant. Once it stops trying to survive, it will just shrivel up and die. This is bad, and doesn't happen normally to a plant that is about to be harvested. Sorry if that was confusing, but I harvested my plant because it died at 5.5 weeks, not because it was ready to be harvested. I was just saying that if your leaves start to dry up, the plant is most likely dead so you might as well cut it down.

In order to check for peak ripeness, you need a 60x magnifier to examine the trichomes. I got a 60X-100X one with a light for like $12 at Radio Shack. That is the only way to truly tell when they are done. Generally, indicas finish between 7-9 weeks although some can go longer, whereas Sativas go like 10-12 weeks +. For example, my Dutch Passion Master Kush usually finishes in 51-54 days, and I had a Purple Kush that finished in 50. Both are pretty much pure indica. I've never grown a sativa, probably because I don't think I could wait that long! :jointsmile:

Hope this was a bit more clear, and I hope your plant can hold out for a couple more weeks and you can still get a decent yield. :thumbsup:
