nutrient burn

[polishpollack]

If you grow in soil don't use 1000. That's a hydroponic ppm level. soil traps nutrients and you don't need to give nearly that much.
Also, don't believe the idea that you have to flush out old nutrients.

I dont


I don’t know my ass from page one but I know what I’m doing is working. Maybe I’m interpreting the results I saw incorrectly but my plants went from distressed to healthy after I started my flush routine so I can only surmise what I’m doing is ok. Also, I always feed the day after and my soil has some amendments such as Dolomite lime so there are some micros for them at all times. Plants don’t go into nutrient deficiency in 24 hours...this makes no sense to me. Shocking a plant with tap water? I dunno man.

Funny thing, I never realized how many theories, opinions, hypothesis and general propaganda there was with growing pot. It’s mindboggling! Lol. No offence and not suggesting anything you’ve said is anything but legit. I truly have no idea...I’m no botonist and the only thing I’ve grown until now is my own hair.

That’s all cool man,,, wasn’t implying you were wrong in any way. all I was saying is that if you flush to clear nutrient build up a slight amount of nutrient does more good that plain water,,,,,
Agreed that you would have to dump atleast 30 gallons on a 12 gal pot to flush it minimum.
This isn’t just some guess out of the blue,,,,it’s tried and true,,,,,, simple as that,,,,, put a pan under your pot and test the run off,,, that will tell you more of what the plant is using than any thing else.
If it’s 1000ppm in,,, and 1400ppm out,,,, tune it down some,,,,
Propaganda,,,,, hehee,,, sry if you felt I insulted you,,, wasn’t my intention.
Back to lurking,,,, it’s much safer,,,,,

Never took anything as an insult. All good. I like to read about other’s various opinions and thoughts...trying to gain as much knowledge as I can!

The reason that flushing with plain water isn't advised, is because plain water will not serve the purpose you are trying to achieve, which is to flush out a buildup. The ions you are trying to get out, are attached by a charge to particles in your soil, and simply dumping water, will not break that bond to release what you want out. Nitrate forms of nitrogen will get leached. So it's better to add namely calcium and magnesium (at least 4:1 ratio), in a sulfate form, not nitrate, as those elements will be able to knock off the elements that are in excess and repopulate your grow medium with a more balanced ratio. Plain water can be used, but as said, it can stress the plant more and require a much deeper flush, with a risk of the problem not being fixed.

Good stuff man,,,, thumbs up if I cld figure out how too,,, oh,, ya,,,

Straight water shocks the plant taking all the nutrients away at once,, also a slightly nutrient flush actually pulls more build up away with less water,, and leaves the plant just enough to recover from the flush,,, you don’t want to stress them for any reason,,,,that’s why they sell plant flush you mix with the water,,, when you flush.
Not all tap water is lime heavy,, depends on yer location...
with pots the size you are using,,, you should NOT,,,,,,, be having any problems with nutrient build up,,,
Just my opinion...
It won’t let me post a link I’m to new,,,,I dig that,,,,
It’s avliable everywhere man,,,, you want cal/mag plus.
Tap iron isn’t chelated......
you’ll get it man,, it ain’t that hard,,,,, just learn from your mistakes,,,
I killed one hell of a lot of plants,,,,,in my day,,, oh,, ya,,,
everyone does at first,,,, if they say they didn’t,, their full of shit,,,,,,
Again,,, just my opinion...

10 4 good buddy. thanks.

Reading you on FM. Thanks.

So in lay terms....how does one go about properly flushing?

As was mentioned, either use one of the many 'cleansing' agents out there, or if you have on hand some epsom salts, that's good as well. Sulfur is a tricky element as it can be an anion or cation, thus it can bond with many elements to help flush them out from the soil and in turn it will also leach out as sulfur, like nitrates, don't hang around too long unless growing in alot of organic matter. depending how bad the medium is, keep checking runoff as you water until you reach optimal ppm's and ph (if that's an issue). Then wait a couple hours and slowly reintroduce a light balanced feed by giving a light water, but not too much water as it will just come out the bottom anyways.

Ok thanks. So for a final flush, should I add Epsom salts? How much water should I run through 12 gal pots and how long before chop do I do this? Thanks again.

Truth be told, i have never flushed prior to harvest as it's only necessary if one has been dumping in more food than needed over the course of the grow. I actually never flush a plant in a normal grow, have done it twice to two sativas as they didnt want that much food and it was stopping everything in early flower, but otherwise, i dont flush. Normally, they say to flush with about 3 times the volume of your medium, but i say flush until your runoff becomes optimal, i say around 400 ppm and then reintroduce a light balanced feed at the end of the flush. You can use epsom for the final flush, keep it low though, i use tap water thats around 140 ppm, and i added enough epsom to bring the water to around 250ppm. As for when to do it? Again, i prefer to feed what the plant wants as oppose to following a preset schedule, so i dont get buildup at the end, so i don't flush, but most people say to start 2 weeks prior to harvest.

Amen on the flush n overfeed statement! It just makes intuitive sense tho go slow n steady on nutes to me. The idea of hammer em, hammer em, just water, hammer with booster and reg shit, hammer w boosters and regular shit and a sweetner, oh soil is all fucked up lets give em a monsoon...flush flush flush then start the same hammer, hammer, bigger hammer nute company pushed bs that got em in trouble in first place! Then its, Oh shit getting close to finish i jammed lots of bad for you chemicals in there i better starve em to death.

Slow n steady wins the race...

I'm like you, The simpler the better and I have started what you said. Half or even 1/4 and they are coming around quickly. RIGHT ON HUCK. Take it to the bank
