I know it's natural for the fan leaves to turn yellow, and they have a few days ago... but now the leaves that have trichomes start about half way... they have lost half or more of their green too. I wish I had pics for you guys but I need to get a new camera. The strain is early bud so it's supposed to be an indica/sativa mix (mostly indica I think) and the buds are nice and purple, but I want purple and green, not purple and yellow.... right? The trichomes have just turned mostly cloudy and the hairs are about 70% red/brown. Should I chance it and go for amber trichomes, or chop it down now before all of the green is yellow?

how long have you been flowering,/feeding and when, what lites are you useing, and how many plants do you have?, need more info so we can help, try to get pics, then you mite get to save your plants, if you show pics, and people mite be able to help, sound like under or over feeding, like i say, need more info so i can help.

I appreciate your willingness to help but I'm not looking for a diagnosis. That's why I didn't post this in the plant problems forum.
It's one plant. I stopped giving nutes two weeks ago because I thought it would be ready to harvest by now..... that's why it's yellowing. I'm looking to see what you guys think about when I should harvest. I don't have any pics and can't get any pics but I thought I described it well enough.
Here are three options I can think of:
1.Chance it by letting it finish and risk having purple buds with yellow leaves.
2. Cut it down now with just cloudy trichomes and 70% red/brown hairs.
3. Give it nutes to give it some life back (but then I'd have to wait a lot longer for the nutes to clear out.

What would you guys do?

Chop it, dry it, smoke it. Needs more Nitrogen sounds like, or maybe girdled. A 10 day flush is enough for me to flush all nutes before harvest and plants do start to yellow really fast.
