Is my Durban Poison ready to harvest?

Durban Poison landrace sativa

It's been in flower for 11 weeks (12.5 since 12/12 switch) and I'm having a hard time telling if it's ready. I have color issues with my sight, I can't tell if the trichromes are mostly clear or white. None look amber. Most "hairs" are red, but some pistils look fresh and clear, which is confusing. I used fox farm fertilizer, nutrients rich soil and I have been flushing for 17 days. Any help is appreciated

These are some of the main colas

Hopefully those help, took them with lights off. Now they looks mostly clear to me. I did dig up an old post on one of the forums where someone said their durban generally took 80-85 days of flower. I'm on day 75-78 today (probably should have been more diligent with dates. I kept track of weeks. Noticed about 10 days after the switch buds started forming to the naked eye, and I switched to flower about 87 days ago.

Definitely! Still quite a bit of clear and a tiny bit of amber starting on your leaves. I'd estimate 2 weeks from what I can see they look tasty! This girl has about a month.

Thank you! So I guess now my main question now is, I have been flushing for over 2 weeks, another 2 weeks would be a month of flush. Should I feed them anything or continue to flush?

Never flush, you basically taking the plants food away from them before they can finish. Yes alot of ferts say to flush before harvest, but it's bro science. Alot of people would recommend to not flush.

---- IN MY OPINION---
Flushing hasn't been proven either way. I'll agree that organic and most soil blends there is no point to flushing, you'll never get rid of all the nutrition, but if you are hydro of any sort (I'm DWC) I encourage it. I catch a lot of flack for my method, people get vehement about flushing and I'm sure someone will respond in kind, but until I'm proven otherwise I flush. Not for that long, going that long you will have hurt your harvest. Not that it won't be good, it just could have been better. My rule of thumb is wait till I think it is barely harvestable and then flush for a week.

I've grown in with just about every method out there. Hydro is no different IF you feed correctly. In your case you probably should as it always seems as though you pump way too much to your plants. Even then if it were me I'd simply reduce the amount of feed and let her ride. As for if it's been proven there are many many ag articles and controlled grows(not just cannabis) that show a reduction in end weight and flavor in flushed vegetables and reduced thc and terpenes in cannabis. I've also ran the exact same strain in the exact same environment flushed one and not the other. No one could tell the difference when smoked and testing showed 2.1% reduction in the terps on the one table and the other was at like 5% terps. That's a vast difference when nothing changed from except the side of the room they were on. I don't remember the thc % but I know it was different as well. To note I did several samples for that run from each table and it was an average but it was enough to solidify my stance after I finished school on the subject.

Also note one of my rdwc builds was a 50, 50 gal totes linked together with 2" pipe and uniseals running off a 275 gal IBC tank and the water was never changed just topped back off pH was auto adjusted and I simply kept the ec where I wanted it. I had recharge in there and a whole host of microbes in that to the point where it should have crawled away.

I have heard this, but it seems to be the most disputed topic.

in your opinion, or anyone elses, am I risking anything by starting to slowly fertilize again for the next week or 2? does 2 weeks of flush followed by 2 weeks of (relatively light) nutrients up through harvest pose any risks?

It's like @Lordhooha said if your feeding right, by the time your plants ready to harvest all your nutrition with watering should be absorbed into the plant. If you are over feeding, ect. Then yes you may want to flush. Goodluck

Ok cool, I heard Durban is sensitive, so have always been on the lighter side. But I will go back to feeding for 7-10 days (so probably 2 watering with nutes) and see how it turns out. Thanks for your help.

They also say they will finish in 8-9 weeks.

Yea I've heard that in my web searches... that's a crock.

So what I'm gathering is that people flush because they don't want to taste the nutes. But if you're tasting the nutes then you likely harvested a plant suffering from nutrient burn right? So wouldn't excessive feeding be dangerous at this point? Through flowering I would often water every 2 to 3 days and rotate between nutes and plain water every other. I can understand the logic if reinstating my previous feeding schedule, but doubling it seems like playing with fire. Isn't the only hard rule for growing to not do anything drastic in a short window of time? I'm all about those baby steps. More concerned with quality over bud size at this point.
