Are these ready to harvest?

Each plant is 63 days flowering. I am so afraid to take one down as I took down my last grow way too soon and it was a total waste.

I really would appreciate your evaluation of these trichs.
Thanks.

I am going to say not yet. You seem to have a lot of cloudy which is good but I dont really see any amber in those pics. Keep a close eye on it, I would expect you to start seeing amber soon.

Full plant pic would help, hard to say from those pic.
Probably done, seems like mostly cloudy Trichomes.

Pics are too close. Trichomes matter when the rest of the plant looks finished.

Here are some pics of the whole plants.

Looks like you got some heat stress judging by those dead tops. And also looks thirsty or overwaterd. If those were mine they would be coming down next weekend.

not done looks like a 9 to 10 week hybrid to me. knowing some genetics would help here but id say between day 63 and 70. peak potency is about a 7 to 5 day window so id say soon. i never harvest all my plants at once at least not on their first run. take one now and take another a few days later or even a couple weeks later. you gotta do some experiments of your own and not jus rely on experience of others. you find the best answer and tell us what weeks is best to harvest that strain.

I don't think these would be a waste to take down now but a few more days it will start turning amber but this is what i ask myself when in your situation. Am I trying to win the cannabis cup? answer Is no and the second question is it likely to swell more? if yes then wait if not then the third question is do I have enough to get by until it is ready to burn? hope that helps you decide.

Like I said it looks close, probably a week left.
It looks like it was Nute burned or over-watered during its life.

Thanks to everyone for their posts. I learned a lot from each of them. You're right about the burn. I don't know if it was heat or nute burn as I was feeding them every other time, but the time when it should have been water only, I was putting in additiives like Nirvana, Open Sesame, and Floranectar. I was doing that for all the plants, but not every one burned. How many mistakes can a person make? When I think that I've made every one of them, I do something else wrong. Haven't had a good grow in more than a year. I really appreciate all of your replies.

Well, it's been 3 days since your trich post....got any fresh pics or have you chopped?
