when to Harvest? pics!

Just wondering when to harvest. my plants are budding. they have been budding for about 10 days. How long should I wait to harvest? Are there any signs? Def. don't want to harvest to early. Is it possible to harvest to late? Here are some pics taken today. They aren't the best. Def. more buds than you can see in the pics! Please help. Any advice is appreciated.

8 weeks minimum. Around the week 7-8 mark, post up more pictures and everyone will help.

if you have a radioshack near you go buy the 60x microscope and check your trichromes.

THey will go from Clear --> Cloudy --> Amber.

Once they are cloudy you will be close. Once like 5% of the trichromes turn amber you should be ready to harvest. The more the amber, the heavier the high, almost too heavy if you wait to long.

Cloudy = head high
Amber = couch ridden high.

Also get some bloom nutrients if you wish, and also give it a little extra nitrogen around week 2-3 of flower to keep it green.

Good luck man.

Also wondering if frost will hurt them?

yes frost will hurt them, cover them up at night.

you still have a while yet but if you follow the people before me advise you'll do great.
