I got the light working again...I'd attached the driver and dimmer to the wall on a mounting board.....I loosened the screws to get at the back reset button and the light went out....looks like I'd tightened it too tight and depressed the reset button disengaging the dimmer and switch......a bit sensitive I mean it wasn't that tight but its now working as it should...panic over light is great. Operator..... well...typical issues...try and do a good job and ooops too fking good ...let er hangFurther to that, I think that's probably why plants grown in a symbiotic media like living soil don't need flushing as often as a soiless or hydroponic grown plants.
Living soil communicates with the plants through exudates and soil microorganisms to only really provide what the plant needs. Whereas chelated nutrients in a hydroponic system is much more like being hooked up to a feeding tube. Whatever I put in there is what the plant is gonna take up. Whether that's too little or too much. But it's almost always a little too much, especially when you're pushing plants hard for production.

Cheers Casimpi, to be honest I learn something cool here all the time myself. Even this latest theory on flushing just formed the other day after watching a video someone here shared featuring Dr Bruce where he stated that there was no evidence that flushing is beneficial. BUT.. he then elaborated to mention that plants CAN store unassimilated nutrients in a similar way to how humans store excess food in the form of fat cells. With plants those unused nutrients get stored in vaccules, which are essentially microscopic sacs that act as a depository for unassimilated nutrients. Then he admitted that if you've been pushing your plants hard with nutrients, specifically phosphorus which is taken up by cannabis in huge amounts and stored in these vaccuoles, it could be beneficial to use only water at the end to allow the plant to assimilate or use up the stored nutrients.Your two part post explaining "flushing" makes more sense than any other explanation I have ever heard.
This is why there is so much debate on flushing vs non flushing. They are both the answer it just depends on the situation as to which answer makes more sense.
Once again I am excited each time I check in on this thread not just for progress picks, but because 90% of the time I learn something pretty cool.
Thank you for sharing your knowledge and keep up the great work!
Good stuff dB! I worry that a lot of people will pick through this post and decide end feed flushing is beneficial. The key here is iff you pushed your plants hard in the grow..Cheers Casimpi, to be honest I learn something cool here all the time myself.

And it's fairly well known amongst LP's and commercial growers now that Phosphorus and Chlorides are the two main nutrients that if left in the plant in excessive amounts, leads to a bad burn quality.
After watching the Dr Bruce video, a light bulb came on for sure.
Real thought and experience goes into your growing mentality, and that’s why your results are so good.Which raises more questions. What's better, to slightly underfeed the whole cycle? or to push them hard and then flush at the end? What is the difference in results?
The way I see it flushing is just insurance if you're not sure. And if you've been feeding chelated nutrients in a soiless or hydro setup with high P values, it's likely beneficial. Imho.
If you're using a soil with a low input of nutrients that have a low P value.. may not be as necessary.
I guess my question is what is gained by pushing them hard vs careful tailored low dose feedings? If this grow is any indicator over previous grows, it looks like I get bigger stickier buds by pushing the P levels up in flower and feeding on the high side. But who knows. Just meaningless observational theories at this point but I like how it makes me think.
I think it's the word that confuses people. "Flushing" cleaning everything out and if you don't you get shit tasting / burning weed...I don't see flushing as in pouring 3-4 gallons of water through a 3 gallon container..or 10 gallons through a 5 gal...some do that to flush I've read...All flushing to me is back to back watering ...in a feed water feed water cycle...with good runoff...I now start that at week 8 in flower...I don't fkin know...I smoke my stuff is that flushing?Which raises more questions.

I do but I'm reluctant to give my opinion just yet. It has been a non stop leap frog in progression the whole grow, one week the HPS plants look better an the next week the LED plants look better.@Dirtbag do you notice any difference in growth under the HIDs vs LEDs?
im with you as far as people getting the word mixed up. The word "Flushing" to me is like flushing the toilet. Massive amount of water to clean the salts down like @Mr.GreenthumbOG said.I think it's the word that confuses people.

would you say the extra P is good for any strain or is it just particularly to your grow?Just comparing photos of my last run to this one it's clear that something is different this cycle. Last cycle I kept P low, had smaller buds and dark green leaves nearly right to the end, and in the end the leaves went dark purple instead of fading properly.
these pics are all of the same strain at the same stage in 2 different cycles. This was last cycle using low P. View attachment 1207602
This run dropping N way back and jacking up the P, the buds are much more filled out and wider, and the leaves aren't so dark green. This is of course proof of nothing as other variables changed too. But it's certainly something I'm seeing visually in the room this grow compared to last and it certainly makes me wonder.

This is only when you have excessive amount of build ups and for the plants sake its better to reduce the salts vs just watering.
However, In @Dirtbag scenario, the word "flushing" the plant, is meant to reduce the nutrients uptake by the plant. imo, this is not flushing, although the word is used as one.

This round I started introducing more P about a week before flip. I started by hitting them with about 0.2ec of mag-pro on top of the foliage pro in the 3rd week of veg. In the first week of bloom I was doing about 70% foliage pro, 20% bloom and 10% mag pro. By the end of stretch it was up to 70%bloom, 20% foliage pro and 10% mag pro (percentage in terms of total ppm, not refering to the volume of nutrient added). Weeks 6 and 7 has just been 50/50 bloom and mag pro, I cut out foliage pro by the end of week 5. Wasn't ever a drastic jump from one ratio to another, it was gradually transitioned throughout the grow.im a sucker for purple lol,. Was it the 3rd week you started to feed more P?
Me tooim a sucker for purple lol,. Was it the 3rd week you started to feed more P?
