New Grower White Widow @ 71 days. Harvest drawing near?

[sturgex]

Hey all, I read this thread (https://www.autoflower.org/f44/when-harvest-autos-your-leaves-will-tell-you-4889.html) and was set on waiting until the fan leaves turn yellow, at least a little bit. But I keep seeing so many grow journals on here for autos that do not have yellow leaves when they're harvested. Just wanted to do a sanity check to see how many folks use the fan leaves as a guide and how many do not, and why.

Pics from this morning

I personally keep an eye on the fan leaves while checking the trichomes with a magnifying glass (or a microscope if you have one).
The trichomes are clear at first and become milky after that. If you harvest at this point you'll get a more clear head high.
After this the trichomes turn amber. The more amber trichomes the more stoned your high becomes. I think most people harvest at 50% to 80% of amber trichomes.
The fan leaves personally I watch to tell me how much longer the plant will go. Hopes this helps and that the pro's will step in with better advice

It works fine but if you want the best that your plant is going to give, use a magnifying glass to look at the trics as Reed said. Personally I go for 30-40% amber trichs.

Excellent. I've got a couple loupes and I can do some macro lens shots with my Nikon to keep an eye on things. So far no amber trics showing.

Found you a picture that I think shows it well, but there are many more of these examples:

oops, thought it was a bit smaller pic. Ah well :dunno:

Thanks! Interesting bit about higher CBD if you let them go more amber. I haven't read that anywhere else.
