Flushing first DWC grow

[Dumme]

Oh, lol. Nah, I never took a picture of the ash from mid-flower. I just know I've done it multiple times, even showed a few different people. I clip bud from a plant, chop it up small, put it in a bowl and slowly burn it. The first few hits evap the water and then the last few tun it to an off-white ash, pretty much the same as the pic I posted.

I started doing that a few years ago, when I ran across people talking about moisture content determining the color of the end ash. Just doesn't wash in my garden. I have a nice camera now, I'll have to remember to take pics this next run.

Like I said, and as goes for all RIU, pictures or it never happened.

I'm just going to assume you don't know your ppm's of Silica and Potassium..

When my wife reads that statement she's going to laugh. RIU will have to wait a few months.

Correct.

I learned what worked 'decent' 15 years ago, from other growers, and haven't broken it down. I fully plan on getting in to custom mixes to further tweak it, don't have the time/resources yet. At this point I've only made a few tweaks that help bring out better quality, and that really didn't take much.

As for silica, unless there's some other explanation for the pH dropping back to 5.4, I'll believe it's due to the silicon I added being absorbed. At that point, it'll be whatever is naturally in the Lucas mix from using GH nutes.

If the pH is dropping, that means you plant is uptaking water more so then nutrients. The nutrients themselves, drop pH. You didnt know this?

Correct.

If you don't even know your ppm's how can you accurately comment on any of this?

Seriously, does not matter what stage of flower, my "wet' bud easily burns to an off-white ash.

I hate to say it Dougles, but with this last statement, I'm afraid your credibility is plummeting.

Re-read what I previously posted.
Liquid silicon acts as a pH UP. I mix my nutrient solution and pH it to 5.4. I then add liquid silicon (as a pH UP), until the pH is 5.8. Within 7-10 days the pH is back down to 5.4. It stops at 5.4 and begins to slowly rise as the natural pH rise from plants absorbing nutrients continues. The first 7-10 days the pH goes down due to how quickly the silicon is being absorbed.

Since all of the pH up effect I added, when I added the liquid silicon, is gone, would you not also expect the silicon that 'caused' the rise in pH to also be gone? Should you have another explanation of where it may have gone, I'm all ears.

Yes, I understand.
Are you familiar of how carbonates work?

Carbonates explain why you're havin a yoyo effect.

 

[Douglas.Curtis]

Only vaguely.

I've used the same liquid silicon throughout flower and understand the negative effect it has on flowers. I have none of that effect when I use it the way I explained. Observation of the quality of the end flowers also concurs with the pH change being from silicon depletion.

I highly doubt it. No offense.

Add a pH up that breaks down or is quickly absorbed and the pH will go down. Exact same effect I'm seeing. The end flowers being highly frangible point toward none of the silicon being present in the flowers. The presence of silicon greatly diminishes the quality for me, it's an area I've paid particular attention to.

Should carbonates have something to do with it, it is not leaving it present in the res in a usable way, so I'm not really interested, they're still out of the way.

 

[Douglas.Curtis]

Considering the change in branch strength during stretch, I'd say the plants are definitely absorbing the silicon. I LOVE silicon for building vascular tissue strength. Plants are capable of higher transpiration rates and support much higher yields.

Lower pH levels allows carbonates to disolve. As carbonates disolve, pH level is driven up. (yoyo) this will keep happening until all the carbonates are disolved. Your "Liquid Silicon" is basically a bunch of carbonates.

Uhh... my pH goes down and I don't get a yo-yo. I get a quick decline, back to the pH level I used pH up to set initially. The rest of the reservoir life is standard. pH rise to 5.8, add nutes to drop back to 5.4, slow rise to 5.8. Lather, rinse, repeat.

The only anomaly is the first week where the pH is dropping, due to the silicon being absorbed rather quickly.

I believe you've begun to overthink what's happening in my res. No worries.

I feel the same way

I'll hit this thread back up when I have some mid-flower burn pics. Like you said, some crowds just have to have pics to believe. I'll see what I can do about a video, so there's no mistaking.

You clearly are misunderstanding what a pH solution is and does. The pH stands for "potential Hydrogen ", and is not the solution itself, but how the solution effects the base mix. The pH itself, is the measurement of the activity of free hydrogen (H+, acid) and hydroxyl (OH-, base) ions in a solution, not the measurement of Silicon thats been uptaken.

Don't worry about posting any pictures, as your credibility is no more. I'm sure you'll just alter the test preformed to subjugate the results in favor your desired pseudoscience.

You've been sidestepping all my response to a potential new debate on new subject, for God knows why, other then to possibly out wit me, and promote this pseudoscience; no more...

Fortunately I'm no longer willing to play your games. The fact of the matter is, you've come to this faults sense of science when growing, and making wild claims, with no real facts to back any of it.

LOL, Cute, but hardly an effective defense.

@Med4us check out the pics bro very similar look to what happened to my pineappleasure express auto in a rdwc. ...interesting thing is the candy kush from same seller has has no problems. Here's a pic to see but idk man I dealt with very similar circumstances would love to know what the outcome was....

too much phosphorus loads your soil/plants with cadmium...and your kidneys hate it. Always use a BLOOM based nute that is low in heavy metals. Even organic fertilizer has it - Humboldt Bloom Natural has one of the highest levels of Cadmium - like 40 times more than AN Iguana Juice bloom.

From my understanding, "Flushing" or "to Flush", as defined by google is:
cleanse by causing large quantities of water to pass through it.
"flush the toilet"

DWC can't be flushed, as you just dump the water and refill. When the term is used in growing Cannabis, it's for cleansing Soil.

People are confused as to "Flush" by cleansing soil, and to "withhold nutrients" at the end of Flower, to break the Chlorophyll's cycle, and speed up curing.

With that said, chlorophyll is, in fact, the number one reason of harsh smoke or chemical taste. **Chlorophyll naturally breaks down*** as the nutrient uptake slows (also naturally) after it's lifecycle comes to a complete end. This is witnessed in nature all the time on all manner of flowers and trees.
The act of Flushing, for better tasting bud, is a complete waste of time.

NPK has nothing to do with smoke quality.

The best explanation of why people forcefully withhold nutrients is to break the internal chemical chain of events within the chloroplasts, hence slowing or stopping the chlorophyll from being produced. Yes, this does happen, and Yes, your smoke may be smoother. But know this.... withholding nutrients he last week's before harvest, you're more than likely going to limit the full potential growth of your plant. Withholding nutrients is not the reason for better tastin and smoother smoke, broken down chlorophyll is.


Why anyone would want to hinder growth and yield for a week or two of time curing is beyond me. Why not just cut early, right? Why not quick dry, right? Heres an idea, if youre gonna spend all that time and money to grow, why not do it right, grow it right, feed it right, dry it right, cure it right, and not take shortcuts. Again, just an idea.


PS, anyone with a curious mind interested in learning more about the chloroplast within cannabis, here's a short clip on it. Expand your mind...., cheers.

Finally...an intellectual response.

It's because you flushed to long . In DEC you only need 2-3 days flush. You caused it to be underfed and caused some defincey because you flushed 2 long also in DWC just drop your nutes back to 1/4 nutes than 1 to 3 days pure water with a flushing agent.and your plants was dark green so you were also feeding heavy. The unbalance is what caused it from pverfeeding to underfeeding so quickly via DWC will cause this
