How soon should I harvest?

trichomes coloration pistil coloration (and retraction, not just from plumping calyx but when they actually start to coil up.) bud density use'em all. it'll make being consistent in future easier. buy a 30x scope -- like a currency checker or jeweler's loupe. they are less than 10 USD typically. later harvest is more sleepy/couchlock buzz for most ppl... but you should experiment with early-to late harvests to find your preference. Chemicals do not always act the same way in each body... some ppl get hyper from Nyquil and some ppl go into a near coma... do yourself a favor and test it out for yourself.

I think you're more than 2 weeks away honestly... maybe 3 or 4 since she hasn't even started her fade and the pistils are still pretty white. Looking nice and frosty, though... it's going to be a great harvest! Keep an eye on the pistils if you can't get in for a really close look at the trichomes... when the pistils are about 90% brown, you'll be good to chop. Good luck!!

from overall look, max 2 away away from chop, would stop all nutes now and go with plain water when needed. have a look at this https://honestmarijuana.com/trichomes/
