Harvest...?

Oh...yeah...I checked your actual diary and I noticed some issues (imo). When I said nutrient deficiency and not excess, that's not quite true, you certainly have excess of some things and deficiency of others. Considering that plant is only week 7, it seems awfully early to look like that. I think development was "rushed" with the additional stress from nutrient imbalance and perhaps excessive light cycle. Usually (though I'm unfamiliar with strain), that would be harvestable around a month later and you'd have a bit more significant (bulkier) and homogenous development.

I would probably even have given it some milk/yoghurt/goat cheese/fermented coconut milk(does that even exist?)/lactic acid bacteria stuff, calcium and citric acid for that last week (well, even before that ideally). The reason is that stuff can increase phosphorus uptake/utilization and "BRIX" or whatever...but at that stage it's probably not all that beneficial.

As braveheart says, you should flush your plant if you have excessive buildups...only then. You should strive to not grow to get excess buildups. From what I can see, you don't have much of that, and in fact even some deficiencies/suboptimal balance (likely phosphorus related). But it's not major. And the darkness thing is utterly pointless, unnatural stress with practically nil use. It's like, just let it grow as per usual, when you're gonna dry it, it's gonna be dark. Imo it's like a mostly pointless "stasis" waste of 2 days. Anyway, yeah, that plant looks about ready to me, but, I can't QUITE say. Cheers.

Hi mate, sounds good but there is no actual need to stress your plant with darkness. Or flush the plant. Both of these are urban myths and only serve to reduce its overall strength. Good luck and happy growing
