Advanced Flushing Techniques

[Jefferson1977]

are you going to do a control with an r/o & tap flush to see any significant differences?

I use lake-water, so it will always have some level of nutrients. In a sense it is a tapered flush. It has an EC of about 0.3.

It's as if all your above posts served no purpose but to allow you to show off a pic of your buds. They do look good but peg down a bit, they certainly don't make your opinion more valued.

I could claim to be a sex god then post a pic of my dick as passive aggressive proof? (not the best example). It's like.. logic, in the mind of the illogical.

Well if I was growing shitty tiny buds my opinion would have less value as far as I'm concerned. This is a forum about growing weed after all.

My well water is only moderately hard. It was at 150 ppm of mineral content when I moved in and after a year dropped to around 100. I think the iron balance that was working great may have changed.

We get buildup on the faucets and shower after some time. But no calcium buildup. Iron.

So my plants are very green and seem fine. The lockup sneaks up on me. I will pay more attention. It’s tough with different strains from seed all the time.

The answer as I found out last night again is to leach the pots every few weeks with a gallon of water only and then a gallon of low like 250-500 ppm nutes.

My burned crispy edges and tips went from crispy to soft. It’s funny feeling a half dead looking leaf and the tan parts don’t crumble anymore.

Looks ugly but the buds are growing great.

Must be calcium or iron buildup. I read with hard water you should use more runoff to maintain the medium back in the jorje Grow book.

Thank you for all the info and ideas.

Ah well that sucks a little, guess you can only work with what you have.

Growing a good plant does not give you a degree in botany, scoring a good goal does not give you a degree in sports science and yes, having a penis does not make me a sex god.

I value your info less now, for the record. Knowledge and application are two different things.

When you say "Flush" it sounds like you mean water only sometimes and leaching in others. It can be a confusing term as it seems to mean two or three things.
I leach when needed (not often as I rarely over feed) and I water only often (my whole house runs on rain water) as I'm a dirt grower.

i thought of using diluted ocean water as a foliar & drenching/tapering off liquid instead of plain ol' tap, but was too lazy to go back to the beach with my gallon jug

I would be careful with ocean water even diluted, the salt/saline content could harm your plants.

If you've been doing it for 20 years it gives you both experience and knowledge, and the application thereof. I do not have a degree in Botany and never said I did, but that doesn't mean NPK aren't mobile nutrients, nor does it disprove anything I said.

Here is my garden and big buds not sure what yours looks like. I'm gonna flush the fuck outta this. In fact I already started. It's going to taste much better flushed.

If you notice a difference in taste between your 'flushed' herb and your 'unflushed' herb then you're feeding your plants too much fertilizer.

People who have grown for 2 year are at the same point you are at, you don't need ''20 year of experience'' to copy what works for others. To fully understand what/why/when/how is a whole other level. Botany alone has changed drastically, never mind the highly misinformed mj side of things. The fact that you are contemplating the details of ''flushing'' clearly shows years of practical growing experience has not put you ahead of the curve.

I'm truly not being a dick or demanding you accept flushing is good/bad, just saying that you don't get to pull ranks.

This is a widely inaccurate statement at worst or a highly simplistic statement at best. You could feed your plants the minimum amount possible and still benefit from some leeching at the end. Just my 2 cents.

I didn't "contemplate" anything, I pointed out that NPK are mobile nutrients and it is possible through a process of osmosis to get them to translocate into the root zone. Then I hypothesized about the results of a study thinking NPK levels in bud would have fallen further if the fans were removed as nutrients were being translocated from the fans into the buds while the plants were being leeched.

You seem jealous bud, just get over it.

Ego is an impediment to learning.

 

[Jefferson1977]

It's a highly contentious issue but no one has proven that leeching at the end results in lower THC etc., so my feeling is you will always have two camps of two different minds on the subject. I grow in hydro with minerals so nothing I have said pertains to organic soil grows.

What about semi-organic?

That's how I grow...

If it's hydro you can reduce feed no matter organic inorganic whatever, but if it is living soil or in the ground you have a hard time any leeching nutrients. Someone else might have some ideas.

And you shouldn't need to leach anything if you fed your plants correctly with proper watering practices. Seriously, if you experience off flavors and salt buildup, you're feeding either too much or feeding the wrong foods. There is no getting around it.

If you want to remove fan leaves one or two weeks before harvest go ahead. With 20 years experience under your belt you don't need me to suggest the negatives of doing that.

I tested 3 cuttings last year. I ran them each 3 times.

Fertilizer to the very last watering but tapered to plant need.

2 weeks water only

And last week water only.

Yield and potency was affected with a 2 week “flush”

Potency was lower with 1 week “flush

Best results all 3 times fed to the end.

I do water only if they are too green and may only water the last time or two.

If I want to leach pots a low dose of nutes works better to clear out excess as salts attract salts.

Also sometimes looser buds tighten up with proper late feeding for me.

I am a consistent light feeder though. The plants need much less than I originally thought.


That is my experience and opinion.

I must admit I haven't been growing for a full 20 years. I have grown indoor and out (mainly out) on and off since I was about 18, I'm 48 years young. Allot of what I thought was beneficial turned out to be complete myth but yet was spoken about and was even mentioned in grow books (no internet back then remember).
I work in the Horticulture industry and live in a farming area. Flush is not a hortie term and ive never heard a farmer use the word. Leaching is for the medium, to help remove excess salts. Watering is simply watering. Fertilizing is feeding. These words don't need to be changed.
Hydro Tomato farmers here do flush their lines at the end of a harvest. But they are not growing anything when they do.
