first of all you should look for the leaves begining to turn hard and crispy as well as hookin upwards. when looking at the trichnomes the best time to harvest is when they have began to turn a milky white color; however if they have began to turn an amber color it is not to late, you can still have a great harvest but be sure to harvest before the hairs and trichnomes turn brown.
Well, i guess i'm screwed then......
My plants are in their 9th week, the leaves are drooped down, and my pistils still white and some are dead, and my trichs are amber. Guess it was a waste of time.....
LOL.....the trichs depends on a persons preference of high and the color combination of trichs when checked under a loupe or microscope. The only way to judge the difference is with one of these two tools., and further more all my pistils turned brown and died.....then regrew again as the bud swelled in the las two weeks.
I would suggest to you my friend....above this....to give advice on the plants YOU grow, not the high dollar seeds us and this man grow, such as PPP, White Widow, NL, Violator Kush......need i go on.
You are gonna ruin peoples grows giving supersticious methods for when to rip the plant out youve been growing for the last three months.
Bro, who started this, get a loupe or mic. and check the trich's. if ya wanna be sure.....Some strains look different than others as they grow and mature, and when they need harvested differs.
