The Great Kiwi Pepper Thread

I think the alkaline soil causes nutrient lockout so the important minerals like iron,calcium,magnesium cannot be absorbed by the plant...hence the yellow leaves. Over watering will also give you yellow leaves.
I have been letting the water sit overnight to let the chlorine evaporate but have not always done this. The rain water barrel should sort that problem out.
 
From my reading, iron (unless its in certain chelated forms), cannot be broken down into a form that can be taken up by plants if the PH is above 7.1. 
 
If you add that sachet to the soil only add the tiny bit and observe. Those plants are really acid loving. I overdid it with something similar (sequestron) and the got the PH got down to <3.5 in some pots lol...yea those plants died. In my defense there was no recommended dosage lol...anyway
 
Ideally, you want to foliar spray with iron to correct the deficiency, while adding elemental sulphur to the soil to lower its PH to unlock the iron that's already in there. If that is indeed whats going on.
 
As for the iron chelate i used, I believe the affected plant is already looking greener on the new growth. I took a picture yesterday afternoon and ill take another one this afternoon so we can see if there's any visible difference.

I think the PH of the runoff is more important that the PH of the water going in.
You may have a high PH water but if your soil is acidic it may balance out.

I agree, but over time,(in pots/containers) I believe high PH water raises the PH of the soil in the container, which in turn would increase the PH of the runoff with it.
I was reading a document from watercare the other day which said they add lime to the water to increase the PH to 8.0 to avoid the rusting of pipes etc. Lime = increased soil ph also
 
edit; i guess the size of the pot/container would also play a role in how easily the water can raise the soils PH
 
Hmmm so dolomite works as a buffer? Being lime, can it not take the PH higher then 7 though? I thought it buffers it from dropping.
What if you added it to soil that's already almost a PH of 8?
 
I cant see dolomite stopping it from creeping up from the continual addition of more lime from the feed water though. 
I can see it would be useful for stopping the PH from dropping, from the addition of composts, manures and neutral feed water. As stuff decomposes its naturally acidic.
 
I could always re-pot into new soil and add dolomite to it before I ever start watering it if it will really hold it @ 7, but I dont think it will since my water has loads of lime in it :(
 
Yes.it buffers to 7.So if you have a soil that is say 7.5 it will bring it down to 7.But it must be dolomite lime not normal garden lime.
You could try adding something to your water to bring the PH down a bit? An acid would do the trick,it wouldn't take much.
 
edit:just check online to see what acid is best.

Cool, ill give that a try then on the next things that I pot up. I do have some dolomite at home so that's easy.
 
I was adding a bit of citric acid to the feed water to lower it when I first had the symptoms. The symptoms went away, and it was getting expensive (@ $2.7 per 100g), and I was getting lazy so I stopped it.
 
Now that the symptoms are back, im back to lowering it with citric acid again. But this time I found citric acid for cheap! got a couple of kg's for $10..that should last me! (from the binn inn for anyone in NZ)

This is what I do too. About 1 cup of dolomite per 3 gallon pot when first mixing the soil and then top dress with a handful and lightly water in every 3 months or so. My water source is about 8 ph and my fertilizer tends to be around there too so this helps to keep things growing ok. I use the same mix for my tomatoes and the extra calcium helps to ward off blossom end rot.
 
Hey guys here are my plants:
 
Half of my outside ones - Swampy your Chocolate Bhut is the tallest one on the left. The rest are Chocolate Fatalii, 2 moruga scorpions, Douglah and 2 7 pot jonahs:

Here is the other half of the outside plants - 7 pot Johah, naga morich, 2 reapers, 2 orange bhuts:
2014_10_29_13_23_22.jpg

 
Swampy this is that Dorset Naga you gave me, it's coming along - that's a 70L pot it's in, you can see how massive it's gotten. Still no fruit though.. just heaps of flowers:
2014_10_29_13_24_25.jpg

 
Here are my bigger indoor plants - some have only just been moved into the pots, some have been in them for about a month - Black nagas, 2 reapers, moruga scorpion, chocolate fatalii, yellow fatalii, dorset naga and peter pepper:

And a few smaller plants, some normal sweet peppers and some ornamentals in those clay pots:

Well, I've pretty much lost 5 plants. All were potted with the same batch of medium I made which wasn't dissimilar from the others, but was a lot lower in worm castings.

Meh.

I'll throw that 200ltrs (5 pbs) on the asparagus patch, refill with fresh stuff and try again as I have a small stadium of alsorts waiting for a place on the team.

What did I do wrong?

For a start I didn't document enough info while I mixed soil.

Over watering? - I don't think so.

Over fertilising? - Its possible. Once again all the exact info is in my head, and stuff often changes and degrades once its stored in there.

I'll flick some pics up later on tonight, all exhibit the same exact signs, should be interesting.

Might even learn something hopefully.

bummer! am interested to see the pics
 
I'll try to be quick and upload some pics now, Mrs dd is ready to stream a movie of some discription.
This is 2 Naga Morich, a choc bhut, a reaper and a yellow bhut.
 
Every thing else seems relatively happy and thriving, these five  started yellowing about 10 days ago. I initially responded by with holding water, then a dose of iron, magnesium, etc along with more dolomite and a half mix of seaweed fert.
 
They're gone, tomorrow night I'll rip them out, discard the medium and start again.
 
But I'd love to know where it went wrong.
 
They were transplanted into a mix of %70 mitre 10 el cheapo potting mix, %20 el cheapo compost mix, %10 very expensive worm castings with about 100 -150 gms of dolomite per .....20ltrs.
 
Watered only when dry, they were the runts of everything I put out, not that that matters.
 
We've had a resonable aphid burden and I have resorted to using a detergent spray mix which would roughly be a teaspoon of generic detergent per 2ltrs.

Dang
Pics will help.How long after repotting did they die?
Click to expand...
About 2 - 3 weeks, but ill thrift set in pretty quickly with hind sight.
The one common factor is the batch of soil.
 
Very similar batches that have shared the same environment and treatments are going well.

No, but they do sit in a straight line in the greenhouse.

Its totally possible it is sunburn, 2 of those pot have already lost plants and been replaced, only to be lost again.

My houses lay east - west and they were in towards the middle on the northern side.

Maybe lay a bit of shade clothe along the roof?

Sunburn in October, its possible.

Failing that I'm all out of ideas.

Hey, cheers Swampy.
 
When I moved my plants into the poly tunnel from under lights some of mine started to burn.That was 2 months ago.I just put a little shad over them and it seems to help and didnt spread
