To harvest or not to harvest?

You are at max THC now.

Depending on how quick it's been developing I'd say about 1 week left if she's been maturing at a quick rate. If she's been slow at maturing maybe 2 weeks left at the maximum. Remember that trichomes on sugar leaves mature quicker then those on the bud.

Is definitely your decision. Potency wise, this will be good. Another week would not increase that. It can surely be harvested, i can see mostly milky trichomes and some amber (even though that seems to be mostly on the sugar leafs, where trichomes ripen faster than on calyxes) But if you want the effect to be more on the stoned/couchlock side then go ahead and give her another week or even 10 days. Its up to you!
