Flushing

Hi folks
I'm hearing so many different opinions on the best way to finish/flush so I thought I would ask the question on here.
What gives the best results?
1. Plain Water
2. A Flushing agent like CAnna Flush.
3. A finisher/flush like Nano 10 flusher.

I bought some Nano 10 but literally don't want to ruin things so close to the finish line.

Thanks in advance.
Dont use canna flush its awful

If your basing it off of breeder "times", don't. Use it as a guide only, as they are never correct, and growing environments differ widely. Your plants will tell you when they are done, and the pics you posted, you have more than "a week or so". As Herb stated above, I wouldn't even start looking until at least 2 more weeks.

I looked at the trichomes under the scope and they are cloudy and the heads are now more mushroom shaped.
I thought that was a sign they were close.
The seed merchant said 55-60 days and I'm day 50 today.

You have to realize that with so many outfits selling seeds and fighting for customers many try and get an edge. Since so many growers use short flowering times as a factor when making their purchase decisions many of the stated flowering times are inaccurate and listed as much shorter than they actually are.

Nearly there now.
1 week to go or there about.
thanks for all your help guys
These plants have at least 3 weeks before they will be properly ripe, possibly 4 weeks. They are currently still covered in white stigma which means they are still growing those buds. Here is how you tell when your plants are finished.

The signs of ripeness are pretty standard for cannabis plants.

First a few of the pistils begin turning color and start receding. Your plant is just starting to ripen. Depending on the strain you could still have two months to go. We're just starting this journey.

Two to four weeks later you'll notice that most of the pistils(>80%) have now changed color and curled back into the bud. It's frosty, way bigger than it was a few weeks ago(aren't you glad you waited), and smells dank! It's time, right? Not a chance killer. Patience is a virtue.

Over the next 2-3 weeks it doesn't look much different, maybe a little more swelling in the calyxes, and the rest of the pistils change over, but the stems are starting to bend under the weight of the buds. These ladies are putting on weight internally by adding density and now the buds are doing their final ripening.

Now you begin looking at trichomes, on the calyx, not the leaves, and harvest according to your preference. When looking at trichomes it’s essential to look at them from the side. The bulbous heads can magnify the opaque stalk under it. Looking from the side allows you to more accurately see the condition of the resin in the trichome head.

There is still no rush to harvest, the window just opened, and you have several weeks before you MIGHT start having to think about it possibly beginning to get too ripe. It takes WEEKS for plants to mature not days.

It is very easy to harvest a plant to early. It is very hard to harvest a plant to late. I’ve never seen someone accidentally wait too long.

That's a damn good right up and should be a sticky somewhere. Unfortunately many go by that chart that says to harvest when 50-70% of the pistils have turned and harvest much too early.

Thanks man, that's why I try to share it with everyone. Its all stuff I learned from watching the plants grow over and over again. Lots of different strains, lots of plants, and in the end, if they were healthy, they all did very similar things when they were ready to.

Its really a shame there are so many of those charts out there, and so many articles just simply pushing the old "harvest early for a sativa high, late for an indica high" crap. Instead of actually teaching people how to grow a healthy plant until its ripe.

To add to this debate, I was talking to someone I know recently who has a master's degree in horticulture, and also occasionally consults for large operations. He was talking about doser setups, and mentioned how some big ops have multiple doser setups, depending on the plant stage: clones, veg, flowering, and finishing when the doser is mostly water. I took the opportunity to ask him his opinion on the hotly debated topic of flushing. He didn't really offer his own opinion one way or the other, and agreed that it is indeed hotly debated, even in the professional world. However he did say that a lot of big ops he knows are running mostly water for the last week or two, but not for the the reason of "flushing" nutes from the plant. The reasoning that he's heard, which seems to potentially make a bit of sense is this: since plants have more difficulty taking up water in high EC concentrations and the fact that cannabis is sold by weight (still containing around 10% water when "dry"), feeding water only gives the plant more ability to "bulk up" in the final ripening stage, thereby slightly increasing overall sellable weight. I thought that this was an interesting perspective coming from someone who isn't into "bro-science", so figured I'd share this perspective.

The power of observation and recording results seems to take too long for most these days.

Instant gratification is demanded.

So he is saying that due to osmotic pressure exerted by having nute salts in the water, by removing them, and just feeding water, the plant is able to transpire more And therefore photosynthesize more?

Its an interesting take, and while i have nowhere near the education level my intuition says the added nutes would help the plant bulk up more no? This is very interesting to me.

Pretty much they feed water and let the plant burn up its reserves, while hopefully consuming more water overall to increase daily biomass growth Via increased water uptake and transpiration?

Yeah, basically. I'm not saying that I agree or disagree one way or the other, but it is a new perspective for me. I don't flush, but I generally cut back on EC towards the end and often run just water the last couple of days, but that's out of laziness mostly, as I don't want to bother having to mix up fresh nutes for the last few days before the chop.
